My name is Richard Donovan and I am from the Elgin/ Toledo area in Ontario Canada. I don't have much information on
this Margaret Donovan (my mother also happens to be Margaret Donovan) but her parents Michael and Joanna Donovan happen to be my great great granparents. They had 8 children and one of them was the Margaret referred to. My great grandfather was her brother Jeremiah. JJ Donovan wrote a book about the Donovan history that should be helpful to you.
