Thanks for your response, Terry. Since my original post in 2000, I have found more information on the Holmes/Wilson family.
My Holmes family came from Market Weighton and Pocklington, Yorkshire, England. My ancestor, Thomas Holmes (1839-1926), seems to be the only one of his siblings who crossed the pond. Thomas was in Market Weighton in 1861, and Sunderland, Brock, Ontario in 1871. I have recently found out that Thomas served in the US Navy in 1865 during the American Civil War, so it appears that he moved fairly frequently.
Thomas married Frances Elizabeth Wilson (abt 1843-1879), widow of William Henry, in 1871 in Sunderland. They had at least 4 children before Frances died in 1879.
Frances Wilson Henry Holmes, daughter of William Wilson and Hannah Carnell/Carnall, had 5 siblings, one of whom, Mary Ann Wilson (1843-1919), married Edmond Morrison (1839-1934)and they lived in Orford township, Kent County, Ontario. I found this information in "Commemorative Biographical Record of the County of Kent, Ontario"which contained a biographical sketch of the Edmond Morrison family.
So, I am not sure if you can tie in to this Holmes family or not. There was an Abraham Holmes in either Pocklington or Market Weighton; I don't remember which, but I could not connect that Abraham to my Holmes line. Do you know where your Holmes family was from?
