Thomas Walker (1758 - 1799) was the father of George E. Walker and an ancestor of the Bush family.
He was born 1758 in Clifton, Gloucester, near Bristol, England. He married Catherine McLelland on 22 February 1785, in St. Andrew's Church, Clifton, Bristol, England. Walker was murdered in 1799 at sea by pirates who were plundering his ship.
Catherine, born in 1770, died on 18 October 1806, in Philadelphia, Pennsylvania, not long after her husband, leaving their oldest son as the guardian for another son and one daughter.
