Hello again, I originally found out where the Mitchell family lived from the Mormon's Family Search Library in London, On. They told me the names of the children and that they were all born in Dundee, Angus Scotland. The explanation I was given for William Mitchell's birth in Ireland was - whoever gave the information about his death didn't know exactly where he came from and just said Ireland !
I have never found a birth certificate for William. He did not come to Canada as a young boy. His parents names were John Mitchell and Margaret Christie Dow. His middle initial (according to the Mormon Library) was B. He could have married in England, or Scotland, or Canada. His wife (if he was actually married), may have been RC. He was buried in a pauper's grave.
I guess there is a lot to find out about William Mitchell's life.
Regards, Gram L.
