Ellen Polson (or Palson in the 1901 & 1911 Census) and Helen Robicheau are one and the the same person... my maternal ggrandmother. Her father William Broughton placed her with the Robicheau's at birth when her Algonquin mother died.

I'm trying to find records of her birth (1863 or 1870 depending which Census records are consulted), she was probably born in North Temiskaming or possibly in Moose Factory up north, where her father worked for the Hudson Bay Company.

She married John Polson around 1888 and died around 1956.
