Naming Help!

We have 10 weeks to go and up until now my partner and I can’t agree on any names. I like more left of centre names. He’s very traditional.

Our surname is Old so it also is an adjective, further limiting choice.

So far, only boys name we can agree on is:

Angus James Old (James is my deceased dad)

Other names he has declined: Arlo, Nixon, Monroe, Boston, Remi, Hendrik

He wants Roy

Girls he is “accepting” of:

Milla Grace Old (Grace is my deceased mum)

Hallie Grace Old

Lennie Grace Old

Trouble is I’m not in love with them either.

Other names he declined: Saskia, Sibila, Avery, Orla, Quinn, Marlow, Mimma

Our dog is Lottie which I love and now regret using. :(

Any suggestions, directions, inspiration would be greatly appreciated. I’m getting desperate.
