I am up in Middlebury, just east of Elkhart, not too far from you. I have a hand written family tree (I believe Elizabeth made it) in my possession. It was very neatly drawn with calligraphy. It lists all the kids of Robbert and Elizabeth. Last year I had it framed so hopefully it can last for many more years.
Here is what I have. Jerome would be my great-great grandfather.
Elizabeth and Robbert are both buried in Syracuse. Robbert's tombstone is the largest in the cemetary. After he died, a couple of the kids went to court to dispute the execution of the will and the price paid for the tombstone.
I have Elizabeth as being born Aug 25, 1826
Here is what I have on their kids.
William Orange Lemon Cory b. 5/17/1846- Nothing anywhere by anyone else documents a William being born to them. However, the family tree was made by Elizabeth, and it lists a William O. Cory. Everythng I have seen only lists an Orange Lemon Cory. The 1850 census lists a W.O.L. Cory.
Jerome J. Cory b. July 25, 1852- Committed suicide in 1892. He was my grandfather's grandfather and he never knew him.
Jeniza Cory b. September 24, 1853- died at 17 and is buried in Syracuse
Partner F. Cory b. December 21, 1866-
James Cory b. January 28, 1856
Harvey Vanneman Lincoln Cory b. June 7, 1860- Vanneman was the surname of another local family and Lincoln more than likely came from the recent buzz of Abraham Lincoln. Married his first cousin Pauline Celestine "Sella" Cory. died July 12, 1912. buried in Syracuse
Dorothy Jane Cory b. April 30, 1849
Alica A. Cory b. December 26, 1863- buried in Syracuse d. about 1952
I have lists of all the Corys on this family line as compiled by Earl Cory at Rootsweb and Cory family Society of America. Let me know if you are interested in getting those.
Hope this helps. Let me know if you would like more. I researched quite a bit and have many documents from Elkhart county records for marriage licenses and land deeds.
