Dear Steffi,Lord William had five sons with Corbetta - John his heir, Thomas, William , Russell,and Robert (our relative).He also had three daughters Augusta,Caroline and Frances. I don't believe they ever married. Lord William was a Gentleman to the Bedchamber to George 11 as Prince of Wales and then King. I have just recently found George in the London Directories.He was a barrister was at Grays Inn. Would so appreciate any information when your time permits on Robert and Elizabeth.Looking forward to hearing from you.
