Baby name too similar to Dads name?

Hello and thank you for reading! My husband and I are on baby #3 and cannot think of any names!! We have a 7 year old named Gavin and 10 month old named Aria. We are expecting a baby boy in June and we are so picky with names and the only 2 we can agree on somewhat are Dean and Ford. I love Ford but he is not a huge fan...we both love Dean but my husbands name is Dan and we worry they are too similar sounding! Thoughts?!
