My great grandmother was Priscilla Mayhew (or Laviere) on some documents. She was the daughter of William Mayhew or Laviere; he was the son of Joshua or John Laviere who was a son of Daniel Mayhew or Laviere.
Priscilla married John Wilson Baldwin-son of Daniel and Ellen (Wilson) Baldwin in Ontario (around Dundas).
I have her siblings as Eliza Mayhew, Sarah Anne Levere, Mary Jane Mayhew, and Catherine Mayhew but with the hodge podge of last names I am not sure this is correct!
John Wilson and Priscilla Adeline had 10 (I think)children, most born in Ontario; they moved to Brandon Manitoba when most of the children were young, and then eventually moved to Woodlands/Warren Manitoba area to farm.
Some of their children still live in this area.
Thanks! happy searching!
