Sorry you are having to scrap a beloved name.

But I totally think you are doing the right thing. And I have friends with the last name Hunt, it IS a PITA name.
My oldest son had a different last name than his father and I and he HATED it. Begged us to change his name (we finally did). He was born to another mother and she used her name, not DH's, since they were never married and she would not allow DH into the picture.
When she gave custody to his father he had her last name, DH & I also had a child together and he was the odd man out in our little family of 4. When his teachers would talk to me, they would call me "Mrs. [BM's last name]" and it would infuriate him no end. He also felt like he was less special for not sharing our last name.
When he was 6 BM & DH legally changed his last name, and a few years back I adopted him, so it is a non-issue now. He has no ill feelings towards his birth mom, it was just frustrating to him to have to tell people his last name was [BM's maiden] instead of ours in any situation where they would assume his was the same as ours... school, doc's offices, airlines, etc.
I have several names I love and had to scrap, it sucks.
