30.7.1809 dine at Bonnycastle's; adv. miss Boyce & Fred. Winsor
Possibly one of the daughters of Robert Boyce appraiser, will PCC 1827, grandfather of George Price Boyce DNB 1826-1897. His will mentioned three daughters, Sarah, Mary and Joanna Petronella, but I could only find baptisms for Elizabeth born 1798, Sarah born 1799 and Joanna Petronella born 1803. If Fred. Winsor was 12 years old (see my entry for him) it was most likely to have been the eldest. Since Frederick Winsor lost his mother when he was an infant, Miss Boyce may have been an older person looking after him for his father
