No Foye Genealogy

I'm constantly surprised by genealogy.  Mostly I get surprised when I can't find things I think should be there, in some way shape or form.  The will of Eli Clark (Jr.) mentions his daughter Hannah Foye.  I wanted to find her husband.  There is no Foy(e) genealogy in the NEHGS library nor in the FHL library.  Go figure.  I've seen the surname many times in New Hampshire and certainly the Genealogical Dictionary of Maine and New Hampshire include the progrenitor James Foy b. ca. 1668 and his children, but not down to where I need the information.
