I wonder if this could be the William Clucas. orphan born in Douglas, that you referenced in your posting and the same William Seymour Clucas that Gary is seeking info on. I found this on the Canada Home Children website.
The 1901 Canada census has him living in Brockville with a Crozier family. His 1909 marriage to Emily Ruth McDonald was in Brockville, Ontario, Canada.
