I contacted Sheila Little through the BT male register, also Nancy Buglass had mentioned her as a possible match for Skyee. Her goats were lovely, and she keeps them all in a big group. I wish I had that amount of space...
I got Skyee after seeing her at Border Union show, Nancy was keen to sell the last few of her goats, and she was well bred up, so should have lots of milk.
There are quite a few Muircock goats around, and they do pop up in older records etc. I don't know much about the history though. I hope that once the BGS gets their new system up and running it becomes much easier to search pedigrees and histories of the prefixes.
