Pedigree Query

Her name is Alberta Bound by Matter of Honor out of Jacquie's girl.

She stands at 15.1hh and I would like to breed her to a Connemara pony who stands at 14.1.
The best would be to get a large pony from this breeding but I would like to know what size is in my mare's background.
I do not know if this is possible to find out but I thought I would give it a try.
Thank you

Tracey

Is this mare a chestnut by chance, not much white? For some reason, the name rings a bell....

she has a small white blaze and 3 white socks, 2 on front and one on hind. She is built more like a quarterhorse than a TB

she is a chestnut
