Boys names to fit in with Elsie and Betsy

[ElBe1214]

I have an Elsie and a Betsy, currently pregnant with baby three, hubby and I have fallen in love with another girls name, but we are stuck on a boys name that would suit?

Ideas please!

Love Elsie and Betsy, I don't usually like names that end in a Y, I'd steer clear if you have a son, imo.

Samuel
Marcus
Finley

Max

My initial thought was Joe for some reason.
