Hello Anne,
thanks for taking the time to reply, although it must be disappointing for some people I think They are the Children of Lady Anne Bourchier, 7th Baroness Bourchier & her Lover John Lyngfield.
She was after all Married at aged 10 to Sir William Parr and they never got together as it were, for some 12 years - But she then Eloped With Lyngfield Then Parr went to Parliament stating a child begotten in adultery and that the said child and all future children she may have shall be held bastards.
Best Regards
Steve
Parr, suffering acutely from gout, died without legitimate issue(?), although records exist of a son, † Robert, from Elisabeth and a son William (Thomas), from Anne Bourchier*,
