Agnes Wentworth was the daughter of Margery le Dispenser, heiress of Nettlestead, Suffolk, by her socially inferior husband Roger Wentworth, younger son of a Yorkshire lawyer.
She married Sir Robert Constable (1423-1488), of Flamborough, Yorks. He was the son and heir of another Sir Robert Constable of Flamborough, by his wife Agnes Gascoigne, daughter of William Gascoigne of Gawthorpe, Chief Justice of the King's Bench (by which wife?).
They had 6 sons
John (Dean of Lincoln)
and 7 daughters
Elizabeth (wife of Sir Thomas Metham)
Margaret (wife of Sir William Eure)
Agnes (wife of Sir Walter Griffith and Sir Gervase Clifton)
Margery (wife of Sir Ralph Bigod)
Anne (wife of Sir William Tyrwhitt)
Agnes (wife of Sir William Scargill)
Katherine (wife of Ralph Ryther Esq)
Sir Robert kept his head throughout the Wars of the Roses, being pardoned repeatedly, and died 23 May 1488, leaving a will. His widow Agnes died 20 April 1496.
Note - Many published Constable pedigrees are confused.
Note - Estimating dates for Agnes depends on whether she was the 1st or 3rd daughter, and on the age of her son Sir Marmaduke, for which evidence is contradictory. Birth in 1435 and marriage in 1453 would be feasible.
