I agree. While there is the largest stable of Appy Gypsy Cobs in the world, quite close to the OP, after seeing lots more pics of this mare, I think she is the product of a light Appy breed, crossed with a possible Gypsy or Gypsy cross. She unfortunately, didn't inherit the huge thick tail from her cob side, but the rat tail from her Appy side.
Regardless, this is a kind and obviously willing girl and one who is dearly loved. Her owner can look forward to many years and lots of fun with this mare.
