Does anyone else have or know where to find these dolls?

I've always loved skulls and bones since I was really little and a few years ago my mom found these dolls and buys them for me every Christmas.

This is my latest addition, I named them Rose and Jack.

Meet Adeline and Ellis

And my first couple, Morticia and Gomez. She gets them from a shop in Westmont, Illinois called The Moondragon, but has no idea where they come from. All of the boxes they come in are unmarked, the stands have no manufacturer name, and when she asks the owner where they come from she just smiles and says "Mexico" and that's it. They get a new set about once a year, I'd LOVE to know if anyone else collects these or knows where they're from!
