I am looking for information on the family of Benjamin Alexander, born 1818 in Fayette County, Pennsylvania. He married Hannah Hudson/Hutson in Jefferson County on 28 Jun 1842. By 1850 he was in Holmes County, Ohio. Benjamin and Hannah had the following children: Tabitha, John, Theodore, Mary Ann, Robert, Elizabeth and Freelove. Benjamin died in Perry Township, Licking County, Ohio on 13 Feb 1896.

I'm trying to determine who Benjamin's father is.

Any help would be appreciated!
