Surname project for Ralstons. All variations of spelling. For USA Ralstons, the names may have come from Scotland, or Ireland, England. For North American, Australian and New Zealand Roulstons, they may have spent some generations in the northern counties of Ireland before emigrating. But we are fairly certain that the Surnames Roulston and Ralston did not originate in Ireland, but rather, came from Scottish Ralstons or English Rollestons. Though we still have much to learn, and each new Ralston male who joins us and submits a 67 or 111-marker sample will add exponentially to the value of the project to all its members.
