I know they're quite American but I love American names & now I live here I can use them!
The surname thing is intentional as my husband is an artist and our surname isn't great so wanted a middlename that could be used as a surname if baby goes into daddy's field one day!
I don't think Lincoln would be shortened to Lin, the only shortening would be Linky which I think is cute.
I really love them all and still can't decide, hopefully we'll know which is right when he arrives.
