Mary Ann and Jacob had eleven children, as far as I can determine.⁽³⁾. Many of their descendants still live in Frederick County.

Jacob died April 22, 1870. Mary Ann died seven years later on May 8, 1877, at the home of her daughter, Sara Ann Baker, in Xenia, Ohio.

Mary Ann and Jacob Miller's children:

1. Rufus Theodore Miller (1825- ?). Rufus was born June 19, 1825. His baptism seven months later was recorded in the Zion Lutheran Church records. He was present in the 1830 census, but he wasn't recorded in the 1840 census, and I have never found a record of him since. He most likely died as a child.
2. Ann Rebecca Miller Magruder (1830-after 1880). Ann was born in 1830, in Middletown. On October 23, 1851, she married Rezin (or Risin) Hezekiah Magruder. The year before they married, according to the 1850 census, Rezin was a saddler and was living in a Middletown hotel. Rezin and Ann had three known children, William, Rufus, and Edward.
Sometime after their marriage, Rezin took over as proprietor of Middletown's Cross Hotel. We deduce this from an item in the November 5, 1858, Valley Register, a local newspaper: a Mr. S. D. Riddlemoser leased the Cross Hotel "from the present proprietor, R[ezin] H. Magruder, Esq., and will take possession on the Monday next."⁽⁴⁾ Six weeks later, tragedy struck. On December 23, while hunting partridge presumably for Christmas dinner, Rezin accidentally shot and killed his hunting companion, Henry Fraley ⁽⁵⁾.
Soon after this tragedy, the Magruders moved to the nearby town of Frederick, the county seat, for that is where they were living at the time of the 1860 federal census. Besides Rezin and Ann, the census records the presence of two of their three children, William and Edward. The third, Rufus, was not present and doesn't appear in any subsequent censuses, so I assume he died sometime between his birth in 1855 and the 1860 census.
In the 1860 census, Rezin's occupation was Saddler. Boarding with the Magruders were Charles and Mary Baton and their six children, for a total of 12 people living in the household. Charles and his two oldest sons were Laborers. Somewhat unusual for the time was the fact that the Batons were free African-Americans living in a slave state just before the Civil War. Race relations in Frederick County were generally good, the County was mostly pro-Union, but free Blacks were still not considered equals in the general population.
Rezin registered for the Civil War draft in July 1863, but this is the last record we have of Rezin. In the 1870 census, Rezin was not present. Ann Rebecca was living alone with her sons William and Edward. Marital status was not asked on the 1870 census so we don't know if Ann was a widow or not. Also living in her household was Ann's recently widowed mother, Mary Ann Miller, her youngest brother, Alburtis, and three borders, Alice, Charles, and Mary Hammer, aged 16, 10, and 7.
In 1880, Ann was still living in Frederick. She was a widow according to the census. Living with Ann was her son William, age 27, a cigar maker. His marital status was listed as married but no wife was present. Also living with Ann was a young girl, Anna, age 6, and boy, Robert, age 4. They were listed as Ann's daughter and son, but they were almost certainly William's children. Also living in Ann's household in 1880 was her sister, Jennie (Virginia Ann Rebecca Jones), her husband and their five children (see below).
I have no record of Ann's death. She died sometime after the 1880 census.
3. Francis Miller (c1833- ?). The only information I have about Francis comes from the 1850 federal census. At that time she was 17 years old, so she was born about 1833. She was not present in the 1860 census, probably having married in the interval.
4. Mary Emily Miller (1836-1839). Mary was born April 27, 1836, and died on April 10, 1839, only days before her third birthday.
5. Susan Ann Elizabeth Miller Quinn (1838-1907). Susan was born April 10, 1838, probably in Middletown, and was baptized a year later. She had two older sisters, but one died on Susan's first birthday.

On July 14, 1853, Susan married John S. Quinn (or Quyun). She was 15, John was 20.⁽⁶⁾. According to a family member, John operated the South Mountain House, an inn on the National Road west of Middletown (which is still operating as a restaurant as of 2019). When John registered for Civil War duty in 1863, the log book had a notation that John had been convicted of a felony, but had been pardoned. I'm not sure what the significance of this is, if any.

We're not sure how many children John and Susan had. I've identified 14 children by this marriage, but in the 1900 census wives were asked how many children they had given birth to, and how many of them were still living. Susan answered she had given birth to 9 children, 8 of whom were still alive (my records show nine of their children were still living in 1900). She should know, but we also know that people occasionally self-reported erroneous information to census takers who were usually local residents. Thus, we need to review the proof of parentage and existence of their 14 identified children more closely.

In the 1860 census, John and Susan were living with John's parents in Boonsboro, Maryland, about 10 miles west of Middletown. John didn't have an entry for occupation. They had three children. Ten years later, the 1870 census shows Susan and John had moved to Middletown. They now had seven children, ages 6 months to 13 years old. John's mother and father were also living with them. John occupation was Carter (someone who drives a two wheeled carriage). In the 1880 census they had moved a few miles east to Frederick, Maryland. They had nine children living with them, ages 1 through 21. John's occupation was "Huckster" (a common term at the time for a salesman).

In the 1900 census, they are still living in Frederick. John is a Tailor. They own their home free of a mortgage. Two single adult sons are living with them as well as a daughter, recently widowed, and her one-year-old son.

A note to researchers: The Quinn's last name was often spelled Quyun and even Quynn in census documents. My best guess based on my research is that "Quyun" was the preferred spelling of many of the family members.

John died September 25, 1905. Susan died November 22, 1907. I'm indebted to a descendant of Susan's, Ann Rothenhoefer Frey for her information about this family.
6. Columbia V. Ann Miller (1839-1921). Columbia was born November 21, 1839, in Frederick County, Maryland. She was the sixth child of Jacob and Mary Ann Miller. Two of her siblings died before her birth, leaving her with three older sisters. She was raised in Middletown where she had friends her age nearby. On October 20, 1859, she married Levi F. Miller. Columbia was 19, Levi was about nine years older. According to the 1860 census they lived on a farm near Woodsboro in Frederick County. It appears Levi's mother and two teenage sisters were living with them, as well as two young single males, (one was a 23-year-old carpenter who owned $6,000 worth of real estate), and a young couple with a 12-year-old daughter. This was probably Levi's family farm which he had probably been farming since his father's death in 1852.

In the 1870 census they were living on a different farm near the small village of Johnsville. Their farm was valued at $7,800 and his personal estate was valued at $1,000. Their four children are present as well as a farm worker and a young girl who helped Columbia with the household chores. Levi's widowed mother was living with them.

Ten years later the 1880 census indicated they were still farming, but there is no way of knowing if it was the same farm. They have seven children living with them now, but they had no hired help living with them (the 1870s saw a deep economic depression that wiped out a lot of people's wealth). The 1890 census was almost completely destroyed so the next time we encounter Levi and Columbia is the 1900 census. In the intervening 20 years, they had moved to Philadelphia. Levi was a grain dealer. Four of their children are living with them, all four were single ranging in age from 19 to 35. They were living in a rented house.

Ten years later the 1910 census shows Columbia was living in the same house in Philadelphia, but Levi was not present. Her marital status was "married" not "widowed" even though her husband had died just days earlier (he died of broncho-pneumonia). Four of her children, all adults, all single, were living with her. She owned the house free of a mortgage. In the 1920 census, Columbia was still living in the same house, her marital status was "widow," and three adult children were living with her, as well as a servant. She owned their home. She was 80 years old.

Columbia and Levi had a total of eight children. According to their son's application to join The Sons of American Revolution, Levi died in 1910 and Columbia died in 1921.

7. Ann Eliza Jane Miller (1842-1848). Ann was born May 13, 1842. She was only five years old when she died on March 26, 1848.
8. Virginia Ann Rebecca Miller Jones (1843-1910). Virginia was born on June 3, 1843 (a previous date of birth reported here was in error) in Middletown. She was Jacob and Mary Ann Miller's eighth child. All her older siblings were girls. On November 2, 1862, she married William H. Jones. Virginia was 18, William was 23. They lived in Frederick all of their adult life. William was a train engineer. Their first known child, a daughter, was born in 1867, five years after their marriage. Their second child, a son, was born in 1870. According to the 1900 census, Virginia gave birth to eight children in all, three of whom had died by 1900.

In the 1900 census, Virginia and William were living in Frederick with two single, adult sons, ages 23 and 18, and a grandson, James Bargis, age 17. James is almost certainly the son of Virginia's oldest daughter, Emma, who would have been 16 when James was born in 1883. Emma is not living with them so we're not certain she is the mother.

William died in 1909, Virginia died in 1910. Both are buried in Frederick's Mt. Olivet Cemetery.

9. Sarah Ann Isabella Miller Baker (1847-1898). Sarah was born September 18, 1847, according to a website of cemetery records (FindaGrave.com). It appears that Sarah went by the name Sallie Isabella as an adult (given names in the 19th century were rather fluid). I'll refer to her as Sallie in this section.

Sallie grew up in Middletown, Maryland, the ninth child of Mary Ann and Jacob Miller. It appears she married Abraham Baker about 1867 since their first child was 1 year old in the 1870 census. In the 1870 census Sallie was 26, Abraham was 38, but based on her birthdate Sallie was actually 22. In that census they were living in Xenia, Ohio. It's not certain how they met since Abraham was born in Ohio and Sallie grew up in Maryland. The most likely explanation was that Sallie traveled to Xenia to visit relatives or to find an interesting job (six related families were living in Xenia/Greene County at the time of the 1870 census) and met Abraham while in Ohio⁽⁷⁾.

Abraham was a harness maker, like his father. Sallie and Abraham were still living in Xenia in the 1880 census. They were living in the same household as Abraham's parents. They had three children living with them, ages 11, 8, and 1. According to the above website, these were the only children they had. None of them are buried in the Xenia (Woodland) cemetery where Abraham and Sallie are buried, so it appears they moved away as adults.

Sometime after Sallie's father died in 1870, her mother, Mary Ann (Levy) Miller, moved to Xenia, for a Middletown, Maryland, newspaper reported that Sarah's mother died in Sarah's home in Xenia, Ohio in 1877⁽⁸⁾.

10. Charlotte Ann Miller (1850- ?). My records show Charlotte was born January 13, 1850, but she is not present in the 1850 census which was taken just six months after her birth. However a Charlotte Miller, age 12, is listed in the 1850 census mortality schedule (which listed everyone who died in the year preceding the census, and their age). I believe this is our Charlotte Miller, and her age given was an error on someone's part. A discussion of my decision can be found here.
11. Albertus A. Miller (1851- ?). Albertus was born in August 1851, in Middletown, Maryland. By the 1860 census, his family was living in nearby Frederick. In the 1870 census, Albertus and his mother were still in Frederick. living with her sister, Ann and Frank Magruder. At this time, he was the only one of Jacob and Mary Ann's 11 children still living at home. His occupation was "cigar maker."

Soon after the 1870 census, Albertus moved to Illinois where he met Susan Holchard. In 1875 they wed. Albertus was 24, Susan was 22. In 1880 they moved to Cherokee County, Iowa, where Albertus bought a farm. In the 1900 census they were living on a farm near the town of Aurelia (Cherokee County) which they owned free of a mortgage. Albertus' occupation was listed as "Capitalist". In the 1910 census, and all subsequent censuses, his occupation was listed as "Retired."

Susan died in 1927. Albertus was still living. Susan's obituary noted that of their four children, three - all daughters - were still living: Minnie, Phoebe, and Flossy. I don't know when or where Albertus died.
