Nothing definite is known pre 1600 Greasley
John Stapleton born circa 1600 was not thought by Alfred Stapleton to have been born in the parish. In his book " A Pedigree of Stapleton of Greasley, Basford and Nottingham"
"All that can be said is that the dates of offspring suggest he was born somewhere about the year 1600" is the relevant passage!
If Alfred could have found a Knightly ancestor, he surely would have! :)
Having said that, There is a John born 20/3/1595 in Partney Lincs and another 14/2/1600
both born to William Stapleton born 18/10/1565 Langton by Partney Lincs.
but no evidence to link to "Our John"
I can expand the tree sideways! for all the branches
