Baby name help

I need help with a new name for a boy. I am due in August and was talking to a family member the other day who is due soon. I told them my baby boy name and they said if they have a boy they have that down as the name they like too. Obviously they will get to choice the name as they are due before me. So now I have to start again with a name however I love this name and I like other names but don't love them. The name is Theo so if anyone can help me with finding a name just as wonderful that would be appreciated. Thank you
