In the 1871 census, Samuel Moore is age 32, living in Esquesing twp., Peel County. With him is an Agnes Moore, a widow in her 60's - his mother? Nearby are 3 other Moore's - John (age 34 or 36, married to a Hutchinson?), William (age 34 or 36) and James (age 30, unmarried living with one of his brothers. All are of Irish descent.
I think that these are the Moore family that I have been looking for - Samuel Moore (my gg-grandfather) married Ada Trueman (whose family comes from the Maritimes) and they move to Halton County. Samuel and Ada probably had 8 children although I only have names for Harley (the oldest), Ida Rebecca, Rena, Lloyd and Myrtle.
If anyone else has encountered this family, I would apprecite hearing from you.
