My 14th Great Grandfather Sir George Anthony St Leger, 1484-1536. The following is from Geni:
Inherited Lundy Eggesford, Annery, Monkleigh in Devon and other properties in Kent and Sussex from his maternal grandfather the Earl of Ormond. A chief courtier to King Henry VIII, his wife was Lady in waiting to Catalina of Aragon and they both attended the “Field of the Cloth of Gold” in France. They also attended the coronation of Anne Boleyn, his cousin on 29 May 1533 in Westminster Abbey. His son was awarded many lands in Devon in Exchange for Kent property owned by his grandmother. “Served” at Exeter Cathedral.
His wife was Lady Anne Bourchier Knyvett
And for One of his sons, the brother of Catherine St Leger, my 13th Great Grandmother the following information Extracted from Wikipedia:
He was the son of Sir George St Leger (c.1475-1536), of Annery, by his wife, Anne Knyvett, daughter of Sir Edmund Knyvett of Buckenham and his wife Eleanor Tyrrell. His paternal grandparents were Sir James St Leger, of Shipton, and Lady Anne Butler, heiress of Annery, daughter of Thomas Butler, 7th Earl of Ormonde and great-aunt of Queen Anne Boleyn. One of his great-uncles was Sir Thomas St Leger (c.1440-1483), the husband of Anne of York, Duchess of Exeter (1439-1476), sister of Kings Edward IV and Richard III. His great-grandfather was Sir John St Leger (c.1404-1442) lord of the manor of Ulcombe in Kent, whose three sons Ralph, Thomas and James, all made advantageous marriages. The manor of Ulcombe had been held by the family from the See of Canterbury from shortly after the Norman Conquest of 1066, during which a St Leger knight is supposed by tradition to have supported William the Conqueror with his hand on disembarking from his ship at Pevensey.
