Yesterday, while reading English Medieval Monasteries 1066-1540 by Roy Midmer (research you know) I found this intriguing snippet under Marrick Priory, Yorkshire: 'In 1536 the rich and beautiful girl, Isabella Beaufort, whom Henry VIII had tried to marry, is said to have obtained sanctuary here for almost 4 years until the house surrendered.'
I am really puzzled by this because as far as I know the last two male Beauforts died at Tewkesbury in 1471, and even if they had a legitimate daughter (which I'm virtually certain they didn't) she would scarcely be a 'girl' in 1536. Their elder brother, Henry, Duke of Somerset, had an illegitimate son, Charles, from whom the present Duke of Beaufort descends, but the surname was and is 'Somerset' not Beaufort.
There's very little about this lady on the internet but that little says she was maid-of-honour to Catherine of Aragon and eventually married her true love. Potential for a novel, maybe, but not for me as I could not bear to write about the ogre Henry VIII. Does anyone know anything about Isabella, particularly who her father was?
