I've looked and, as far as I can tell, there isn't a Formby in New England. There is, however a New England Guest House in Formby.

Even if there was a Formby in New England, Formby would still be Formby which, as it happens, is in Merseyside although, when my father was growing up in Freshfield, it was in Lancashire. It's been there for over a thousand years and is under no obligation to change its name. If there was a Formby in Massachusetts, it would be called Formby, Massachusetts.

But there isn't.
