I am searching for any information on the st. clair/sinclair families.James Sinclair came to PEI early 1800's.Two of his sons were John and Robert.James left PEI for St. John NB and was never seen again. Someone found his grave by a Presbyterian church, I have no idea which one, and there are many tales about Jamie and his wandering feet. None of the family knew where he was or what happened until his grave was found. His sons John and Robert changed their last names to St. Clair and moved down to Veedersburg Indiana. John a painter and Robert a carriage maker.Robert married Clara Emma Lombard. I cannot find out who James married, all family tales just mentioned James and they lived in Summerside. Any help out there?
