Jan. 4, 1902

Andrew Roehm, born Feb, 12, 1814, died Jan. 4, 1902. Friedericke Roehm, born Feb. 245, 1827, died Sep 9, 1910. ROEHM
Andreas “Andrew” Roehm was born in the Kingdom of Wuerttemberg on 12 February 1814, born in what looks like Celm, Wuerttemberg, in Zion Lutheran Church Schumm’s records. [Could be Chelm?] According to the 1900 census Andrew immigrated to America in 1836.
Andrew Roehm married Catharine Bienz (1819-1858) on 16 August 1840 in Van Wert County.
In 1840 Andrew and Catharine lived in Tully Township, Van Wert County. In their household was one male aged 20-30 and one female aged 20-30. One might assume it was Andrew and wife his Catharine, although her name was not given. 
According to the census enumerations it appears that Andrew and Catharine had at least 8 children, although enumerations before 1880 do not show family relationships. Their supposed children are listed at the end of this post.
The Andrew Roehm family in 1850: Andrew, 37, Catharine, 31; Mary, 9; John, 7; Elisabeth, 5; Jacob, 3; and Christian, 1. The parents were born in Germany and the children were born in Ohio. Andrew was a farmer. 
Catharine (Bienz) Roehm died in 1858 and is buried in northern Van Wert County.
Sometime between 1850 and 1860 Andrew Roehm moved to Willshire Township. He likely moved after his wife’s death since she is buried in northern Van Wert County.
Widower Andrew Roehm in 1860, enumerated with his children in Willshire Township: Andrew, 45; Mary, 18; John, 16; Elizabeth, 14; Jacob, 13; Christian, 11; Christian, 11; Henry, 9; Emanuel, 7; and Anna, 3. 
Widower Andrew Roehm married Friedericke Gutheil on 8 November 1860 at Zion Lutheran Church, Schumm. Friedericke used her maiden name Gutheil on their church and county marriage records, but she had been married before.
Friedericke Gutheil was born in Germany 24 February 1827 and, according to the 1910 census, immigrated to America in 1849. Friedericke married John Rettig on 21 January 1851 in Franklin County, Ohio.  It appears they had at least 5 children.
Friedericke’s husband John Rettig was not enumerated in the 1860 census with Friedericke and the family and one might assume that he died before the census was taken. Their youngest child was 2 months old when the census was taken on 23 July 1860. Counting back 9 months, John Rettig likely died between September 1859 and July 1860.
Friedericke (Gutheil) Rettig resided with their [supposed] 5 children in Willshire Township in 1860: Friedericke, 34; Charles, 8; Mary A, 6; John, 3; Frederick, 1; and Catharine, 2 months. This enumeration indicates Friedericke was born on Schrozberg and the children were born in Ohio. It does not indicate if Friedericke was a widow. 
The Andrew Roehm family in 1870, with Friedericke’s children from her first marriage: Andrew Roehm, 56; Freidericke Roehm, 43; Jacob Roehm, 23; Henry Roehm, 19; Emanuel Roehm, 16; Anna Roehm, 13; George Roehm, 8; Magdalene Roehm, 6; Susannah Roehm, 4; Rosa Roehm, 1; Charles Reddig, 18; Mary Reddig, 16; John Reddig, 13; Frederick Reddig, 11; and Catherine Reddig, 10. The parents were born in Germany and the father Andrew Roehm was a farmer. 
The Andrew Roehm family in 1880: Andrew, 66; Friedericke, 56; Catherine [Rettig], 18; George 17; Magdalena, 15; Susanna, 14; and Rosa, 11. 
By 1900 the Roehm children has left home and Andrew, 86, and his wife Friedericke, 75, were living by themselves. However, they were living very close, if not on the same farm, to their son George Roehm and his family. This enumeration shows that the older couple had been married 39 years, married in 1861 and that Andrew had immigrated in 1836. It also shows that Freidericke had given birth to 10 children and 8 of them were living. It does not show the date of her immigration. 
Andrew Roehm died of old age on 4 January 1902 and was buried on the 6th. He was 87 years, 10 months, and 20 days old.
Widow Friedericke Roehm resided with her daughter Mary Anna (Rettig) Grund and her husband George Grund in 1910: Friedericke “Ricki H” Roehm, 83, widow; George Grund, 65, head; and Mary A, 55, wife. This enumeration indicates that Friedericke had 10 children, 6 of whom were living. 
Friedericke (Gutheil) Roehm died of old age on 9 September 1910 and was buried on the 12th. She was 83 years, 6 months, and 15 days old. The Zion Schumm’s records indicate that she was survived by 15 children, 14 child relatives through marriage, 29 grandchildren, 4 greatgrandchildren.
