Also, while I don't love it, Amon apparently has Hebrew and Anglo origins. I've heard it as a Scottish name but never as a Jewish name, though. The point is, there are names with overlapping origins if you hunt a bit. I'd start with this list:

Some don't sound familiar as Jewish names, so I'm guessing they are using some algorithm that selects for "Hebrew origin" which is very broad since so many names evolved from Hebrew in the same way many evolved from Latin or Greek (old languages). But if you look through, you will likely find names that resonate with both of you and can compare against lists of names popular in England or Scotland.
