Is this name too out there?

Hubs and I are due soon but don’t know the gender. Where I’m stuck is I love love the name Mattisen for a boy— Matt, Mattie. I don’t know why but I’ve just really liked it for a while. He’s not against it but not completely sold. I do love the name but kind of thinking it’s too out there or abnormal. I feel like it could be decent but looking for opinions as I don’t want to be another tragedeigh 😵‍💫

Do you think it’s too out there? We do have other names as well:

-Roman Rocky (Roman— I fell in love with the name Roman when I heard it on the Red Sox baseball player— huge Boston fans; Rocky after the movies as Hubs and my dad love the movie)

-Beckham Boston (as you can probably tell we want either a Boston or Boston sports tie as I’m from there)
