With the brothers you have listed, I like Abram...but as a name, I love
Bram. Yes, there's the
Bram Stoker thing, but I don't think the connection is overwhelming.
Abram I'd stick with the biblical/hebrew references-
Ezra,
Ruth,
Susannah,
Eve etc.
Bram would be more flexible- biblical names like Ezra/Ruth/Eve, but also "jazz" names like
Art, Chet/Chester,
Etta and older european names like
Adele and
Tilda,
Linnea...
