I don't care for either.
Lincoln is too surname-y, and
Indiana is a place name, which I care for very few only, and I don't find it at all masculine (and to say it was
Indiana Jones' name is wrong, as his "real" name was
Henry; he took the name
Indiana from his dog - haha). Liking American names are OK, even if you're not American.
My vanity requires an audience. - "Washington Square"
