_Jack and Gill_ (Vol. vii., p. 572.).--A somewhat earlier instance of the
occurrence of the expression "Jack and Gill" is to be found (with a slight
difference) in John Heywood's _Dialogue of Wit and Folly_, page 11. of the
Percy Society's reprint:
"No more hathe he in mynde, ether payne or care,
Than hathe other Cock my hors, or Gyll my mare!"
This is probably not more than twenty years earlier than your
correspondent's quotation from Tusser.
