Boy/girl twin names

[Mysteriously]

We're expecting twins, boy and girl and I'm not sure where to even start on names. We already had a DS called Nathaniel. I like quite classic names but nothing that's too popular at the moment. I've always liked Jemima for a girl but DH doesn't like it at all. Some suggestions would be really helpful, on middles names too, I'd like them both to have two middles names

Love Jemima can't you compromise?!

If you like Gus as a nn, consider Angus.

I have a Gus who is really Fergus, (family name).

I really like August as a name, but think Augustus is a bit OTT.

I also really like Angus and, maybe it's a bit of a stretch, but maybe Magnus could become Gus too.
