I am interested in your reference to a George and Jacob Ludwick in Stark Co., Ohio. The wife Susannah Loutzenheiser, however, does not ring a bell.
I have a George Ludwick, born in Pennsylvania, who moved to Franklin Twp, Stark Co. (later renamed Summit Co.), Ohio. He had sons Samuel and Jacob Ludwick. After Jacob Ludwick's death his family moved to the area of Ionia Co., Michigan. They are also in surrounding counties in Michigan.
