Finnian is cool. But hard to put in a combo! I’ve had a go with various different styles:
Finnian Andreas
Finnian Michael
Finnian Santiago
Finnian Matthew
Finnian Thomas
Finnian Jack
Finnian Oscar
Finnian Luke
Finnian Jasper
Finnian Jethro
Finnian Nils
Finnian Samuel
Finnian Emmanuel
Finnian Gabriel
Finnian Elijah
Finnian Scott
Finnian Dakota
Finnian Douglas
Finnian Harris
Finnian Cael
Or just pair it with any name you like, not ending in an –n, and see how it feels to you.
