that is a sweet find!, congrats! Something like that doesn't pop up everyday.
Talithi Cumi is Aramaic for "maid arise". The motto is taken from Mark 5:41 when Jesus raised the little girl.
Coolest thing about this hobby is a guy can find one little thing in the ground, then, before you know it, I am reading/learning stuff I have never heard of, glad you found it. Congrats!
