My grandmother's surname is Gloy. Is this Irish?

Answer 1

It isn't Irish.

The ancestry book of surname origins (see resolved Q for link) doesn't have it. I tried the Mormons for you. There are Gloys born in Prussia, Denmark, Germany and Estonia. There are a few born elsewhere. People emigrate. It looks Baltic from that evidence.

Here are the results. The link is in the resolved Q also.
