ah, apologies, that makes two of us then...we ladies would have had a good chat.
Nicholas Twigge was nephew to Thornhill. His mother was Thornhill's sister & in true Derbyshire style he went on to marry his first cousin who was also a Thornhill from Stanton Hall... So when he was in business with Thornhill Jnr (Henry) this was his brother-in-law and first cousin. Therefore the link to Thornhill family is a lot stronger than you'd think.
