I see your John Eck is from Bavaria and immigrated to IL in the 1830s.
My gr grandather Charles W. Eck (Karl) was from Bamberg in Bavaria according to his Civil War records and the census.He lists his father as DNR (?) Eck and mother as Barbara Link on the Civil War records.His obit lists a sister as Anna Braun but I know nothing of her at all.
He immigrated in 1854 and lived in Cincinnati after the war until his death in 1932.
Any possible link or souce of information would be greatly appreciated.
