Ontario Currans?

Hi there

I am looking for my great grandfather's second family. His name was Ray Curran, and came directly from Ireland. He married a girl in Cape Breton, and they had a couple of children, one of them, James,  my grandfather. He moved to Ontario and met another woman, married, had children and opened what I understood was a garage of some type. There is a possibility that his second family knows nothing about his first family. If you have a relative Ray Curran, red hair, was a baseball player in Ireland. Maybe he spoke of Cape Breton, I would love to hear from you. :) Thanks
