I had put my genealogy on hold since last fall and hadn't noticed the replies.  Please accept my apologies for not replying.
Robert, It would be great if we could find a connection somewhere for Alexander and William!  Somewhere I read that Alexander was a blacksmith in Scotland if that helps at all.
Hazel, about your reply #15, thanks so much for trying to find parents for my Alexander.  I think the family tree you found was mine on "A.......".  It's Stevenson/Hawkes.  I can't prove or disprove that he was born in Glasgow, the information was from his death registration.  A frustrating family to research - the first few children were born in Scotland and I can't find any records online for any of them.  And it's unfortunate that they emigrated to Canada before the 1841 census - they came here in 1834 to farm.  We are still farming the same land today and I think that's pretty cool!  
Thanks again
