I've got a Margaret Echlin who was born n 1876 who married a James LaBelle, in Dalhousie Township... The branch of the family that changed their name to Ecklin did so, I believe, later in time (it was one of the sons of my great-great-great? grandfather) and can be found around Vancouver in Canada. But as early as you're looking it tends to get a little foggy from what I've found, so it could be this is one of the unaccounted for branches of the family. Where did you find your information?
