I have found these place names on family histories of people who had links to Lewis County. I can't place them in Lewis county, and the GNIS page have no entries for Mount Bay, and none for Londonberry, but several for Londonderry. This is searching the whole country, not just New York. If any of you can think of a place whose name is something like these, or can suggest a better place to look, I'd be grateful. I know how place AND people names get mixed up as they pass down through families, so I know I may be looking for "someplace else", and I'm open to suggestions! Thanks in advance, Linda in Utah
