Ok, I looked her up on Data Source and I see she's got a pretty nice dam line. That explains her substance. She's Saqlawi al Abd in strain, traces back to *Urfah, one of the original mares imported by Homer Davenport, considered to be a very spirited mare. Her sire is considered Egyptian bred or related. He traces back to *Nedjme on his tail female line, she also was imported to America by Homer Davenport and used in his breeding program. *Nedjme was so highly thought of by the Arabian community in those days, that she is listed as the first Arabian to be registered in the Arabian Stud Book. She was considered to be Kuhaylan Ajuz in strain.
Really nicely bred mare! And pretty too!
