Natahlya was Nasib x Al Zaiyanna ( Ahmoun x Luda). The marking could have come from the Luda connection or Golden Cavalier. I think the most likely one is Cavalier.
Tina in the New Forest is Tina Banger (think she might be married now though) - she is a lovely lady. Don't think she breeds anymore but when she did she did mostly breed Crabbet Horses and the odd foal by Blaklord Ceasaro.
She had some mare on loan/lease from Mr Plaistow at one point (fantastic mares of excellent breeding)
I have Tina's address which I could email to you if you want to make contact (assuming that she still lives at the same place?).
Tina had an amazing knowledge on bloodlines etc and an excellent photo collection, if your mare was bred or owned by Tina she would I am sure have some great history info for you.
Hello Angieb Please could you e mail me on ken.lovett2@btinternet.com I will get in contact with the lady & fingers crossed she may have bred her! x Michelle x
