nannyj,
Thank you for checking the registers & for your comments. As far as I know, there were only two Robert CORNELLs (spellings do vary as you say) in Saffron Walden at the time who were the 'son of Robert'. The one baptised in 1578 who died two years later, and his father who continued siring children up to his own death in October 1592. So the younger Robert cannot be that who married Agnes DRIVER in Fulbourn in 1598 as has been suggested. I would really love to link the Saffron Walden CORNEWELLs & those in Fulbourn but, to date, nothing has emerged to establish any such connection. Thanks again.
