Abraham and
Joshua work! It's good to have it paired with another biblical name, that way it becomes less president-y. When I saw it at first I thought
Abraham Lincoln, but when I saw it paired with
Joshua I thought of
Abraham from the bible. It's a good combination!
Bram is okay I guess. I don't really like a lot of the nn's for
Abraham, but I like
Abe or Branny better. I knew someone with this name who went by Abra! It was strange but unique.
