My Family Tree

Two families are from Janice Casselman <roncasselman@sympatico.ca>, but note the dates don't seem very likely

Some trees note marriage of Thomas Collins and Anne Christie in 1829 Armagh, Ireland. Some Christie's in Dundas, Ontario descend from Robert Christie b.1796 Armagh, Ireland. Robinson neighbors in Williamsburg also came from Armagh. It's true there were numerous Collins in Armagh but they all seem to be Catholic. Also seems unlikely they would have no children before 1842.

Ann must be his 2nd wife, and most of the children attribute to Mary Ann Robinson are hers. In 1851, Williamsburg, Dundas, Ontario:
Thomas 44 Ireland
Ann 39 Ireland
Margaret 9 Finch
William 8 Williamsburg
Robinson 7 "
Thomas 4 "
Ann 1 "
all in "Church of England"

All still there in 1861 + Mary and Edmund.

Marriage of Margaret Collins and George Merkie gives her parents as Thomas and Ann.
Death Cert of William says parents Thomas Collins and Annie Christie.

Thomas is a miller in the 1851 Census. He could have first settled in Finch to work the mills there:
"Situated on the Payne River, this stream was named in honour of Allan Glen Payne, one of the township’s first four settlers. Using the waterpower from the river, Jerry Merkley, Mrs. H. McMonagle and Mrs. Gordon Ouderkirk built local mills."

A strange entry for a Charles Collins in Tecumseth, Simcoe, Ontario:
Charles Collins 21 1844 County Clare Thomas Collins Ann Collins Margaret Irwin 22 1843 Albion William Irwin Margaret Irwin 20 Apr 1865 Simcoe, Ontario, Canada
