I have been searching for information on a Jacob Acker born in PA in 1823. He died in Akron, OH 26 Sep 1893. In the Medina County, OH 1850 census he had a son Henry - Henry was 3 mths old, but in 1880 census Doylestown, Wayne County OH, only Elias born 1863. Jacob married Eliza (last name not known). She was born 1 May 1821 in PA and died in Akron, OH 19 Dec 1891.
Does this tie in with your Acker family? Were they from Germany? I have descendant information, but nothing on Jacob and Eliza's ancestors.
