Do you have anyone with another Down breed - Southdown, Hampshire or Dorset Down? All Down breeds , including the Ryeland, had a hefty dose of Southdown a couple of centuries ago, and the Southdown itself had a dash of Merino around 1780, which is why the fleece is so fine. Don't go for a show type, as these have an increasing amount of French Southdown blood, so a much bigger frame (although it's hard to tell how much is the result of large amounts of cake).
