Faequine on Family Tree Circles

I know alot about the history of my own family, Terrault and Woodcock, going back 6 or more generations in Canada.

My husbands family not so much. His mom, a Carter, has about 4 generations history in Canada. But of his father we know almost nothing.

All i know is that his name was Robert "Bob" Welch, he left his wife and 2 sons when they where queit young. My husband figures he was about 3 or 4. Last contact from his father was in 1987, Black Friday after a destuctive tornado stuck Edmonton, AB. He called from some where in BC. That is all i know, and i would like to find out anything about this man or his family. Oh, he had a previously relationship before my husbands mother. He has breifly mentioned having older half siblings, i guess him having younger half sibling is a possiblity too.

Any help would be great.
