Check out "The history of morris dancing, 1438-1750", by John Forrest, or "History and the morris dance from its earliest days to 1850" by John Cutting (father of Andy)- both available from Amazon.

Forrest danced Cotswold with Datchet and Oxford University morris (also danced for a while with Earlsdon before he emigrated to the USA), John Cutting with Herga and Grand Union (the Cotswold Grand Union based in Denham, that is).

I met and chatted to Terry Pratchett at Bob and Julia Hawkes' wedding in Saffron Walden in 1992 when I was dancing with, squire of, Flowers of May, so read "Lords and Ladies" with great interest....
