This is years late in answering the $64 question. Her name was Susanna Victoria Stauss, who was married to my many times great grandfather Andrew Kerr (pronounced Car in Scotland - hence the mistake in the spelling of Carr) she was born in Philadelphia, her father was Balthazar Stauss.
Susannah Stauss Kerr Bongard (and later it seems Pierce) lived a good portion of her life in Marysburgh, ON (5th Town). She had many children with Conrad Bongard (Bongard's corners is a small place in Prince Edward County). There are many Bongards and Kerrs still in the area.
I hope that helps.
