There is another connection that Abraham Lincoln's family tree intersects with the Chapin tree. The connection is through Charles Bradford Isham 1853-1919 who married Mary Todd Lincoln (1869-1938). Charles is a direct descendant of Deacon Samuel Chapin through Catherine's line. Lincoln Isham (1892-1971) is their son and the great Grandson of President Abraham Lincoln. He is a 7th great grandson of Deacon Samuel Chapin.
Lincoln Isham had a stepdaughter Francis Mantley (1908-1983), but no other children.
