He was united in marriage with Sarah Michael in 1854. Had fourteen children, of whom nine are living. Jacob, the subject of our sketch, was born in 1836, and reared on the farm. He celebrated his marriage with Sarah Shank in 1 854. They are the parents of three children, viz., Permelia, Almira and Lawrence L. Mr. Baker has followed the occupation of tilling the soil to the present time, with good success. He cast his first vote for “father Abraham,” and has since been identified with the Republican party.
