Born: March 27 1818
There is no record, that I can find, of Jacob serving in the civil war. He would have been in his early 40s.
I have been unable to locate Jacob & Lydia in the 1870 census. There are two other Jacobs in the same area, around the same age, at this time, both in the census:
Jacob born Dec 11 1821, son of David & Catherine (Kepner) Sulouff, married Keziah Kiser
Jacob born July 1823, son of Jacob & Eve (Thomas) Sulouff was married to Mary Catherine Brackbill.
John, David & Jacob were brothers, making all 3 of these Jacobs grandsons of Johannes Zulauff
