Unfortunately, yes. I think I've mentioned all of those names (I swear I've mentioned them all) to my husband. He is just so picky! The good news is that he really liked Rhett Maverick! I think it's Adorable too, especially paired with Callen or Ivy or Cora. I just need some time to sit on it and fall in love with it :) maybe a different mn would be better?
I'm glad he seems to like Rhett (have you considered Everett with the NN Rhett? I like Everett even more than Rhett myself), that'd be a solid name choice. I'm not such a fan of Maverick as a MN, but Conrad would be awesome (Conrad is one of my top names ever, I think it's kind of amazing. IMO it'd be the best first name choice of any you've thus far mentioned)
