Coughton had belonged to Guy Spiney
WikiTree shows Guy being survived by a son Thomas, but VCH says he had no sons and settled the reversion of the estates on his daughters.
I don't know when he died, but Eleanor had probably had her kids by then, presumably at Throckmorton, in Fladbury, Worcs, where her husband John was buried and she founded a chantry.
Hist Parl doesn't think that John was ever knighted.
Thomas (also not knighted) was the eldest son (we make him 2nd). He acquired the other half of Coughton from his mother's sister. No telling where his kids were born.
A John (not the Suffolk John) was the obscure younger brother of Thomas (and also not knighted). Described as of Tewkesbury, Glos, later of Harfield, Glos. Not shown in the Norfolk and Suffolk Visitations. The Warks chart calls him "Thomas Junior"
and calls his father Thomas as well.
He's said to have been beheaded with Owen Tudor in 1461. His wife was probably related to the well-known "Brydges" famyly. Not seeing much info about kids, but there's a compiled pedigree in Vis. Glos
which gives him a daughter Cicely as well as a son John. The descent is followed by Collins
rehashed in Burke's Extinct
