Specifically North European Short-tailed (NEST) or (NST)
There is just something special about them. Started with sheep that eat seaweed, almost entirely seaweed. Then sheep without herding instinct and in a place that seems inaccessible today yet 2,000+ years of dwelling and genetically distinct between the small islands in the archipelago. Where did they come from, who brought them here and how long did this take?

This list is largely based on the article “North European short-tailed breeds of sheep : a review” by Ólafur R Dýrmundsson and Roman Niżnikowski
Dýrmundsson, Ólafur & Niżnikowski, Roman. (2010). North European short-tailed breeds of sheep: A review. Animal : an international journal of animal bioscience. 4. 1275-82. 10.1017/S175173110999156X.
Some Scottish sheep are in this category. Spread of these sheep occurred in several waves Vikings between 700 and 1000 CE, previous ocean fairing people between 300 and 700 CE into the northern Atlantic and others before bringing sheep out of the Near East.
Naming determined by face color, horns and coat in the Medieval to Middle Periods (Ryder, 1984). Specific naming examples of this system are Scottish Blackface, Whiteface Woodland, Devon Closewool, or the German moorland breeds below with heath as the last quantifier.

A second migration, theory by Sherratt, could be supported by genetic evidence (Chessa et al., 2009; Sherratt, 1981)
