The president's branch of the family is believed to have been extinct since its last undisputed, legal and known descendant, Robert Todd Lincoln Beckwith, died on December 24, 1985, without any acknowledged children.
[2][3] Edward was the only son of Richard Lincoln (buried 1620 in the graveyard of St Andrew's Church) and Elizabeth Remching.
By convention, his son Edward would inherit the lands and holdings in Hingham, Norfolk, but Richard's 4th wife had instead convinced him to leave the entire proceeds of the will to her and his three youngest children.
He was born in a one-room log cabin on Sinking Spring Farm near Hodgenville, Kentucky, to Thomas Lincoln and Nancy Hanks.
She had a daughter and a son, both with her first husband, Warren Wallace Beckwith: Lincoln Isham married Leahalma Correa.
