Amber's nice I like that name.
I don't mind McCartney or any similar surnames to
Macauley because one of my childhood best friends / grandma's neighbours was called
Macauley and because I knew him from a very young age, it's a name that I don't initially associate with being a surname. I have fond memories of eating square-packet cheese on the trampoline, drinking pop from the kiddie bench, simply walking into his backgarden uninvited to use their swing (I was allowed to) and talking about pokemon cards.
McCartney gives me the same vibes, but that's very personal to me.
Having said that, I wouldn't personally choose either
Macauley or McCartney as names, it's not my style.
