baccatum Where did PeppaPeach come from? Anyone know the parents?

Grew out a PeppaPeach this year, seed from TexasHotPeppers, and wondering about the lineage of it.
Baccatum really seem to have the full range of citrus flavors, don't they? These taste like something between a Pink Grapefruit and a Mango. Kinda weird by themselves, but great with chicken! I've got the PeppaDew out there too, but haven't sampled it yet.
