Apparently the COLWELL family moved from Armagh, Ireland to Scotland in the 1840's. Its not apparent whether John died in Ireland or Scotland. Elizabeth and her family lived in Dundee, Angus in 1851 and her sons John and James emigrated to Canada in the mid 1850's and settled in Bruce County, Ontario.
Wilfred CRERAR, is a direct descendant of the captioned couple. See Wilfred's Pedigree Chart.
