"The Month of May" (also called "The Haymakers" and "The Merry Haymakers" is in the Laurence Price file on my website. He wrote it in 1656 as "The Country Peoples's Felicity". "The Shepherd of the Downs" should be "The Shepherd Adonis", a populat song of c 1730 (also in 'Scots Musical Museum' with tune).

According to Mrs. Kate Lee (in the 1st issure of JFSS, 1899) who collected the songs from the Coppers in 1898 (6 being in the 1st issue of JFSS) the brothers were William and Thomas Copper.
