This might be the one, but I am doubtful. Her son, my great grandfather, Angus Stewart didn't come to Canada until 1857. The name of the "accoucheur" on the birth registration of his daughter in 1873, was "Isabella Rutherford". I believe Angus to be the illegitimate son of an Alexander Stewart in Scotland who was married to somebody else with whom he had 8 children. But who knows? Thanks for your interest, Virginia
