I am not sure of the parents of John Clark that married Ruth Hamilton c 1819. I know Ruth's background from Henry Hamilton married to Mary Rice. Have a will of Archibald Hamilton and Mary McGregor the parents of Henry Hamilton. Do not have a marriage date of John Clark and Ruth Hamilton. I believe John may have a brother Samuel and Jonah Clark that were born in NS and came to Ontario, Canada. Know they lived in the same area and Jonah Clark signed for John Clark to marry his second wife Charlotte Mills. John received land from a William Clark and Mary in Ontario. Know William Clark came from England with his four children and without his wife, Dorothy Stonehouse. He married a Mary James, widow. Haven't proved for sure any connection. I have two grants for a John and William Clark from New England to Ontario from Lord Talbot c 1823. Know their is smoke just can't find the fire. Louisville, KY USA
