How did they leave out Wm. Strode at that last click-on, 'Cavalier Poets'? His popular style is much closer to broadsides and folk songs than any poets (and a few of his did get on broadside ballads. His "Ballad of the Caps" is in Pills to Purge Melancholdy, and is one of the oldest pieces in Pills) listed there (who are poets, not songwriters, I forgot if Richard Lovelace was there. He wrote a memorable song "The Pensive Prisioners Apology=To Althea from Prison - Stone walls do not a prison make, Nor Iron bars a cage... If I had the wings of an angel, over these prison walls...)

Most in Pamelia, Melsimata, and Deuteromelia is late 16th century (most there being being found in the Lant MS of c 1580)

1632 is a very bad year for looking at songbooks and manusripts for songs (but poems, yes), but a pretty good one for broadside ballads, and I've already told you how to search for them in a broadside ballad index.
