Boy name help for baby 3

[namehelpplea]

We’ve found out we are having a little boy. We already have Theodore (Theo) and Isabelle (Izzy). But are struggling for a third name we can both agree on.
I love Oliver (Ollie) but we are unlikely to be able to use it (was a significant partner for my sister for nearly 10 years and not the nicest of splits). My partner likes James but I’m less keen.
Help!

Samuel/Sam would be lovely with your other names.
James/Jamie is timeless, and goes well too.

What about Robin?

Theodore, Isabelle and Jeremy
Theodore, Isabelle and Dominic
Theodore, Isabelle and Adrian
Theodore, Isabelle and Fraser
Theodore, Isabelle and Benjamin
Theodore, Isabelle and Sebastian
Theodore, Isabelle and Cameron
Theodore, Isabelle and Nicholas
Theodore, Isabelle and Alexander

Another vote to Lawrence.

Or Dominic
Sebastian

I love Matteo/Matthias (Matt)
Other options:
Lucas (Luke)
Joshua (Josh)

Thanks everyone. Have given me some more to think about. I won’t share which but unfortunately we can’t use some of the best suggestions due to nephews/uncles etc but it has given us a few more to think about.
