This is the tombstone of Catharina Schüler, located in Zion Lutheran Cemetery, Schumm, Van Wert County, Ohio. The marker is inscribed:
Hier ruhet in Gott
Geborn 21 April 1810
3 Deceb 1838
Translation: Here rests in God, Catharina, wife of Michael Schüler, born 21 April 1810, died 3 December 1838.
Maria “Catharina” [also known as Katherine] was born 20 or 21 April 1810 in Ruppertshofen, Württemberg, the third child of Johann Georg and Anna Maria (Fisher) Schumm. Her tombstone actually has both dates on it. There is a plaque on the back of her tombstone that indicates she was born on the 20th of April while the inscription on the front shows her date of birth as the 21st. I believe her date of birth is accepted as the 20th, but I am not sure where the information for that date comes from.
Catharina immigrated to America with her father and four brothers in 1833. The Schumms lived in Holmes County, Ohio, for several years and Catharina married Michael Schüler there on 22 November 1833.  The rest of her Schumm family purchased land in Van Wert County and moved there soon after. According to the records of Zion Schumm, the Schumms, and probably Michael and Catharina Schüler and their family, arrived in Van Wert County on 7 June 1838.
Catharina (Schumm) Schüler lived in Van Wert County only a few months before she died on 3 December 1838. She was the first person to be buried on the ground that would later become Schumm Cemetery. A little less than eight years later her father was laid to rest next to her.
A metal plaque is mounted on the back of Catharina’s grave marker and is inscribed:
KATHERINE (SCHUMM) SCHUELER
Born in Ruppertshofen Germany
April 20, 1810
Died December 3, 1838 the same
year the Schumms settled in
this area. She was buried in this plot on high ground in the forest
that later became Zion Lutheran
Cemetery, becoming the first person buried in this cemetery.
Michael and Catharina (Schumm) Schüler had the following children:
Magdalena (1835-1916) married Johann Bienz
Rosina K. (1837-?)
