Sir Robert Brent, of Cossington, Kt. - Parents

This site:

shows the John Brent who was married to Joan Latimer (2nd wife) as the grandparents of this Robert who married Margaret Malet. Grandfather John's first wife was Ida Beauchamp and they're the ones who had a son named Sir Robert Brent, but that Robert was married to Jane Harwell.

I posted in another discussion that there seems to be an extra generation here on Geni, with confusion of various Joan Brents. I believe the Joan Brent attached as this Robert's mother is incorrect and that his paternal grandmother was Joan Latimer. If the two Joans connected as wives of his father merged together and disconnected as the mother of this Robert but instead merged with his grandmother Joan Latimer, I think that would make the Geni connections match what is at the link shared above and with the profile notes in the About section of this Robert's grandfather John:

John Brent

"John Brent, of Cossington, son of John, I Henry V (1413), was twice married; his first wife was Ida, daughter of Sir John Beauchamp, of Lillisdon, knt., by whom he had issue Sir Robert Brent, his successor in the estate of Cossington, and Joan, first married to Thomas Horsey, of Horsey, Esq., and afterwards to Thomas Tretheke, of Tretheke, in the county of Cornwall, Esq. To his second wife he married Joan, the daughter of Sir Robert Latimer, knt., by whom he had a son called John. Sir Robert Brent, his son by his former wife, and heir to this estate, married Jane, daughter of John Harewell, of Wotton, in the county of Warwick, who survived him and had this manor for her Pg. 106 dower, which was, after her death, together with the rest of the estate, entered upon by Joan, his sister and heir by the whole blood, to the exclusion of John, son of John Brent by the second marriage. But this Joan being in a state of insanity, the fines that were levied in her name were not sufficient to bar the heir male, who after several suits at law, and at length an arbitration by John Hody (afterward chief justice of the King's Bench) 10 Henry VI (1440), was adjudged the right heir, by virtue of two entails made in the time of Edw. II, and Ric. II (1307; 1377), and soon after this manor was again entailed to this John Brent and the heirs of their body forever. ' The eldest son of this John Brent was called Robert, and married Margaret, daughter of Hugh Malet, of Currypool, by whom he had another' John, who added to his estate the manors of Goodwin's Bower and West Bagborough, which he purchased of Thomas Godwyn, as also (from his wife Maud, the daughter and co-heir of Sir Walter Pouncefoot) the manor of Compton-Pouncefoot, and Pouncefoot Hill, all which descended to William Brent, their eldest son, under age."

because those profile notes align with what shows at the provided link with the genealogy; i.e. that grandpa John was married twice - first wife was Ida Beauchamp, 2nd wife was Joan Latimer.

Ida was the mother of Sir Robert Brent. Joan was the mother of a son named John Brent who was the father of Robert Brent who married Margaret Malet, not Joan Malet:

"Sir John Brent of Cossington, married, first Ida, the daughter of Sir John Beauchamp, of Lilisdon, Knt., by whom he had Sir Robert, who succeeded him in the estates of Cossington; and, second Joan, the daughter of Sir Robert Latimer, Knt.
A son of the second married, Sir John, succeeded to the estate of Cossington (upon the death and exinction of the line of his half-brother, Sir Robert Brent).10
' His son, Sir Robert, married Margaret, the daughter of Hugh Malet, of Currypool.'

Everything really seems to be in all the notes already but somehow things have gotten mixed up a bit.
