Ok, now this one is puzzling me.
I wanted to contact the previous owners of the horse that I bought, to see if I could follow her lineage down and find out more about her breeding.
The woman I bought the horse from, said she was not able to tell me, because when she purchased her, part of the conditions of the sale was that she not reveal the previous owner's name.
I did find out that my mare could have been registered when she was born, but the owners of her Dam did not pay the owners of the Stud the stud fee, so they refused to issue papers for the foal.
Would that situation be the reason these people don't want their name revealed?
