I am looking for any information or family who may be related to Henry SAMS born in 1752 in Germany. He married Abigail (last name unknown) in 1775 in New York. Immigration date unknown but I would like to find someone who may know it. Henry died in 1818 in Ohio. They had a son named Abraham SAMS born 1784 in New York. He married Sarah (last name unknown) in 1807. He died in 1860 I think in Pennsylvania but I am not sure of this. They had a child named Henry Calvin SAMS born in PA in 1808. He married Elizabeth GROVES in 1836 in Ohio. He died in 1865 in Ohio. They had a son named James Harrison SAMS born in Ohio in 1839. He married Eva ROLLF (spelling may be wrong) in 1876 and died in 1920 in Iowa. Their Daughter Eva Minnie SAMS born in 1879 in Iowa married William Franklin KEITH in 1893. Their son Harry KEITH born in 1902 in Iowa is my great grandfather. He married Mable WARDLOW.

I would like to find information on:
the parents of Henry SAMS and his wife.
the names of Henry and Abigails children.
and the names of the children of their descendants.
