Can we please get back on the subject of Gallóglaigh. This is the Historical Arms section, if you want to debate ethnicity make a thread in the Off- Topic section.

Thanks very much for those images Sean.

I'm researching something else but by chance "Scots mercenary forces in Ireland" opened on this:
"There is a particularly Scandinavian feel to the galloglaigh origins. why Gall-oglaigh,. for example? The Irish never referred to the Scots Gael as "gall" but the mixed Scandinavian and Gaelic race of the islands and west highland forelands was called gall gaidheal as a matter of course and without explanation by the annalists.......it is interesting to note that annalists referred to the Hebrides as Insi Gall-the islands of the foreigners..... buannacht....is a Norse loan word."

Of interest is that the in the Gaelic South West we also have gall-gaidheals in an area with profound Norse cultural and possibly genetic influence. Just over the modern border in Cumbria norse derived dialects continued almost to modern times.

FWIW, the Trachtenbuch of Cristoph Weiditz has an example of women's clothing in Ireland around 1530-1540. The extremely large sleeves seem to be a constant for both sexes.
