Re: William and Sarah Callam in Callam's Bay Ontario
I think we may be looking at the same family,
my gggg/grandparents were John Callam & Anna Moir
their son John Callam (b14/2/1773) married Margaret Farquharson (b1779)
Their Children were;
John 1804 (M)Margaret Hay.son Alexander(M)Mary Ann Reid.
Margaret1816(M)William Douglas.son William(M)Isabella Reid.
Alexander Callam & Mary Ann Reids Daughter Was Maggie Callam (my Grandmother).
William Douglas & Isabella Reids son was James Douglas (my grandfather).
So as you can see both my grandparents are related directly to the callams (and the Reids)
