I have 1200 names in my data base, mostly from Ontario Canada and am attempting to connect these families to a common ancestor in Ireland. Our own great, great grandfather is William Sixsmith, born in Queens County, Ireland who married Eliza Booth. In a research trip to Ireland we contacted a Sixsmith family that told us the family stories were that their Sixsmith family married the Booth family in Canada. The Booths lived next door in Ireland. I would welcome anyone doing research on this family line and am willing to share my well-documented information.
