All the information I have is second hand from people who did research into the early pioneers of Ontario Canada so I can't vouch for it's authenticity. Was hoping to get some proof myself.
Those are the sibling names that I have. It looks like William, Benjamin and Robert emmigrated to Canada for sure.
Also two half siblings, "Big" James Anderson, b-1793 in Co. Tyrone; also emmigrated to Canada and Irvine/Irwin Anderson, b-1795.
Like I said though, nothing documented....
Off to FamilySearch.
Thanks!!!
