A lot of females don't have adam's apples. It's a male characteristic, like having a beard. Of course there are women who do have beards, but it's not the norm.

As for Mr. Coulter, that picture of a child may or may not be Ann, it's a child and doesn't mean anything one way or the other. In her case, not just because of the adam's apple, but also because of the large hands and feed, and the fact such a Christian lady didn't get married and have children, I truly think she is a man. I won't believe otherwise until she verifiably given birth.
