Robert Kernohan, born 1815 in Dundee Scotland, moved to Antrim, Ireland at age 4; moved to New London area, Middlesex, Ontario Canada in 1848 with his wife Martha Barr and two children, the baby being buried at sea. We know a lot about Robert but nothing of his parents while we know about Martha's parents and a grandparent. Makes me think they died young or there was a problem.
I've searched Scotland's people and PRONI and Canada archives. I do think I found them on the 1851 Canada census with the last name spelled KARNHON. They might have been living with an Andrew KARNHON, age 61, born Ireland.
What else can I do to find his parents? People have asked questions in Ireland to no avail. This is my main brick wall.
