I didn’t want to make this more confusing than it is; that’s the reason I did not include the following information.
I obtained a copy of the marriage license of William Wadsworth Jr. and Celina Romain from the parish in Westmeath, Ontario.
William states his father’s name is William Wilwith (could be the French interpretation of the name WADSWORTH) and his mother’s name Bridget Conley.
Reference to Catherine Hennessey’s baptism in Buckingham 1839, what was her mother’s name? I am not enrolled in Ancestry at the moment so I cannot follow your link.
