This is the tombstone of Martin Geisler, located in row 5 of Zion Lutheran Cemetery, Schumm, Van Wert County, Ohio. The marker is inscribed:
Hier ruhet in Gott
2 September 1852
Alter von 52 Jahren
Here rests in God, Martin Geissler, died 2 September 1852, age 52 years.
Martin Geisler was born in about 1800, according to Zion Schumm’s records. In all probability he was born in Germany.
This appears to be the Martin Geisler family in Willshire Township in 1850: Martin, 50; Anna, 44; Margaretta, 19; Michael, 21; John, 16; Barbara, 12; CM, 6; Theodore, 3; and Catharine, 6 months. Martin was a farmer. All members of the household were born in Germany, except Catharine, who was born in Ohio.  This would indicate that the family immigrated about 1858. Also of interest is that the Martin Geisler family was enumerated next to my great-great-grandfather Louis Schumm. They lived very close to each other, possibly next door to each other.
Martin is mentioned in Zion Schumm’s records only one time and that lone entry is his death and burial record. That record indicates Martin Geisler died 2 September 1852 at the age of 52. He was buried on the 3rd.
Other Geislers attended Zion Schumm with Martin and they all may have been related in some way. Some of these other Geislers include:
