If your Chester Ertle died Jul 13 1994 in South Haven Michigan, then he is the same Chester Ertle b. March 14, 1910 Jay Co. IN son of Jesse Ertel & Cora Cross! (My understanding is that Cora married a 2nd time, I have some notes from another descendant, will try to locate, but some of the info was confusing and I had questions. Do you have answers?)
Jesse Ertel was born Feb 11 1882, Jay Co. IN, a son of James Ertel & Precilla Allen.
James Ertel was born Jul 12 1842 Warren Co. OH, died Mar 11 1926 Jay Co. IN, a son of Daniel Ertel & Lydia Booram.
Daniel Ertel was born Oct 8 1797 Northumberland Co., PA and died Nov 6 1878 Warren co., OH, a son of Daniel Ertel & Catherine Myers.
Lydia Booram was born abt 1802 in Hamilton Co., OH and d. Dec 6 1870 Warren Co. OH a dau. of Aaron Booram JR and his 1st wife (still researching her exact name, but poss. Rebecca Harris, Quaker disowned for mou 1785 Loudoun Co., VA)
See other postings on this forum regarding Daniel (SR)and his parents Valentine Ertel & Sophia Mohr.
If you e-mail me (firstname.lastname@example.org) I can fill you in on additional details I have on the Ertels of Jay Co IN & Warren Co. OH as well as the ancestry of Lydia Booram back to the immigrant Willem Jacobse van Boerum from Netherlands to New Netherland (LI, NY) in 1649.
