I have something a little different.Thomas and Philippa did hav a son, Thomas, b. 1428 (Baker's History of Northampton and Metcalfe's Book of Knights of England) but I have him married in 1456 to Marina Beler.
Thomas Green who married Ela Malorie, I have as being born 1413, the son of Henry Greene b. 1375 and his wife, Margaret. (Henry was the son of Henry Greene and Matilda Maudit.This Henry was a brother of Sir Thomas Greene, who was the father of the Thomas Greene who married Mary Talbot)
To get back to Thomas and Ela's line...they had at least one child, John, b. in Gillingham, Dorset.He was known as "John the Fugitive".His birth date is given as 1448 and 1468 in different sources.(His parents married circa 1430).John had a child, Robert who had houses at Bowridge, Dorset and Bramdeane, York, married in 1519 to Johanne Leyg at Rotherham, York.They had at least 10 children, one of whom, a son, Richard 1530 - 3.5.1608 who married Agnes Hall 26.11.1545 at Dewesbury, York.
