Baby Name Poll

We need some help! I like really different (not necessarily unique but uncommon) names like Felix and Sebastian and my husband actually likes all the names I like (except a few). The issue is we don’t know if we should go down the path of more common names (we love Mason, Dominic, Jake, and Liam) or for more uncommon names (Felix, Sebastian, Riordan). My other issue is my dad just passed away and we want to include his middle name (Sean) but my husband also wants to have a child named after him! His name is Mathew. Is there like a different form of Mathew out there so we can still name him after my dad and my husband without having confusion whenever anyone calls the name Mat? The only alternatives I can think of are Mateo or Mathias and I don’t like those. Please help us!!
