Elizabeth died June 17, 1875 in Ontario. Martin married 1 or 2 more times before moving to the West Coast and he went between the US and Canada. So apparently did the family I believe it was Michigan.
Their son was James Alexander Brackett and he married Margaret Thatcher. Their oldest (William Ross) was born in Ontario and then they moved to British Columbia where their other children were born.
I was contacted about Jonathan Brackett and his family history.
