7" porcelain baby doll

I have two of these beautiful little dolls but don't know who they are.

Their marks are hard to read, and don't know where to start. They have open mouths with 2 teeth, red painted toes and fingers on their composition bodies.

On the back of their heads at the top of the mark is a 22 on the bottom a 4/0. The mark is a circle with a line through most of it with a cross line separating the bottom. It might have the initials M A on either side. Dolls are 7"
