My grandfather James Cronshaw came from England and settled in Woodbridge, Ontario Canada, this outside of Toronto. His wife Alice was Valleyfield Quebec, Canada.
They had several Children. Who had several children. All mostly living in Woodbridge, Ontario, Canada. and the surrounding Ontario boarders. Maybe this is the person you are looking for. Please post more message on the board and I will research some more.
The Cronshaw's are not a common name. Lets see if we can put together a tree.
