I also did a search for the names, and only Carolinia Belle is listed in the AMHA. Neither of the other names are listed, although there are other horses with the same farm prefixes. So neither other mare is registered in the AMHA

I also did a name search in the AMHR for the mares, and can find no horses that fit the names of Gypsy Roselee or Midnight Roselee. There is only one horse listed for 'Roselee' spelling. I also searched all horses with Gypsy, and can't find one.
I think this breeder may have purchased unregistered horses, and is now passing them off as having had their AMHA/AMHR papers, but they never did.
I think you have gotten good advice here -- find 3 other mares that are REALLY registered.
OR -- do you have the W papers? Who is listed as the sires and dams of these mares. Perhaps I can look up their sires and dams with birthdates and find them. It's possible their names were changed when they were registered in the "W" and the names you have are not the correct ones for the A and R. Just a thought.
