Name troubles

Holly
My husband and I are having a hard time deciding on a name for our little boy. He like Lucas and I like Liam. Well I should say we both like both names those are just each of our favorites. I have a cousin that had a little boy named Luca that passed away not long after birth. I think that Lucas is too close to Luca... my husband doesn't. I'm not close with this cousin, but I still feel really weird about it. Any input would be appreciated!
