Hey Randy, I'm in Luckey, Ohio, now, but my "branch" of Grosjeans came from Curtice which is a stone's throw from Williston.Who is your father / grandfather / etc.?I may be able to trace it all out.
My dad is Al Grosjean, son of Edward Grosjean and Lillian Cedoz (another common name in the Curtice-Williston area).I believe Edward's father's name was Joseph.Oh jeez,just realized I may have some of those names confused.
Our family farm is still on Curtice Road between Fostoria Rd. and Bradner Rd.My dad's brothers are Donald, Willard, Leonard (dec'd), Wilson (dec'd, twin to Willard), and his sisters are Alma (twin sister) and Jeannette (dec'd).
Check out the cemetery some time at St. Ignatius -- there are quite a few Grosjeans there.
