I believe this song was composed by a mistral,in the time of Henry 8. The manor houses of that time had minstral galleys,used by companies of minstrals, in a school I went to had a minstral galley.I dont except the Anne Bolyen story,she wouldnt keep using the same blouse over and over again,I believe greensleeves was a member of the gentry possibly daughter of the squire ,she was well above the mintral in her station.
