Francis Percy Snr. (who claimed before his son Francis Jnr. to be de jure Earl of Northumberland). Genealogical chart III and his brother Thomas our claimed ancestor established this connection and as grandchildren to the Plotter that as well.
Francis Percy and his brothers are also in or St Mary Magdalene line as well as on Chart III and Francis' brother Thomas born in 1622 may be John Purse/y's father.
