This is the tombstone of Maria Schinnerer, located in row 6 of Zion Lutheran Cemetery, Schumm, Van Wert County, Ohio. The marker is inscribed:
Hier ruhet in Gott
Den 23 December 1842
Den 2 September 1870
Translation: Here rests in God, Maria, wife of Martin Schinnerer, born the 23 December 1842, died the 2 September 1870.
Maria Schinnerer was born Maria Schumm, the second child of Ludwig and Barbara (Pflüger) Schumm. Her birth predates the Schumm church records, which begin in 1846. However, both her marriage and her death are recorded in the church records.
Maria married Martin Schinnerer on 23 February 1860. According to the church records “Anna Maria” Schinnerer died 1 September 1870 at the age of 27 years, 8 months, and 4 days. She was buried on the 2nd. This date disagrees with the death date on her tombstone by one day.
Martin and Maria (Schumm) Schinnerer had the following children, per Zion Schumm’s records:
Georg Friedrich (1861-1935) married Wilhelmine “Minnie” Roehm
Adam Wilhelm (1862-1862)
Heinrich Adam (1863-1913) married Minnie Richter
Johann Jacob Friedrich [Rev] (1865-1950) married Anna Evers
Susanna “Barbara” (1866-1952) married George M. Schumm [son of Jacob Frederick]
Johann Ludwig (1870-1870)
It appears that Maria (Schumm) Schinnerer may have died as a result of complications of childbirth. She died a day or two after the death of her last child, who was only 14 days old. A tombstone does not appear to exist for that child, Johann Ludwig, who died 31 August 1870.
Maria’s husband Martin Schinnerer was born in Bavaria in 1834 and came to America in 1852. He was the brother of my great-great-grandfather Friederick Schinnerer. After Maria’s death Martin married her sister Rosina. They were married in a civil ceremony by Thomas Cully, JP, on 2 March 1871.  According to one source, Martin’s second marriage was not allowed at the church so they were married by a Justice of the Peace.  Their marriage was not recorded in the Zion Schumm’s records. Martin and Rosina moved to California around the turn of the century and remained there the rest of their lives. Martin died in Los Angeles in 1930 at the age of 96.
The inscription on Maria’s tombstone is a little unusual because it shows her birth and death dates, instead of only showing her death date and age. You usually have to calculate the date of birth from a tombstone inscription of this era. According to her tombstone inscription her age would have been 27 years, 8 months, and 10 days, which is six days off from the church record. Perhaps math wasn’t the minister’s best subject or the tombstone was carved incorrectly.
