Young girl cradling a lamb in her arm.

Hi guys, I am new here and have no idea how things work, so please bear with me. I got this figurine at auction from an antique store and I have searched for info for days with no luck. I’m hoping someone here can solve my mystery. I didn’t know before I bought it that the store owner had marked it as c.1865, but I can’t confirm that. It is pretty heavy for a figurine and is 8” tall. It has a clear glaze on the base but none elsewhere. The only markings I can see are some scratched letters under the bottom the begin with X. Help!!
