There was a Tunis Acker listed with spouse and a daughter and a son in the 1803 Adolphustown, Prince Edward County, Ontario census. In the 1851 census of Blenheim, Prince Edward County, Ontario, there is a Tunis Eckert born 1778 in New York with his wife Rebecca . Their listed children are William D 31, Nancy (could be a wife of William D) and Tunis Jr. 18. I have researched my line of Acker that came from Dutchess County, New York to Brighton in Murray Township of Ontario. Relatives of this family that were born in Ontario relocated to the States. The use of this same name that means Thomas(Tunis is low Dutch) probably connects through generations.
