Peter's elder daughter, Elizabeth, was brought up in the family's lovely Edwardian house in Battlefield Road, St Albans. After living in Toronto and then in Melbourne with her first husband, she returned to England and was with her father when he died in 1983, aged 65, from the rare genetic condition of M.E.N.1, which she unknowingly had inherited from him. After moving up to the Yorkshire Dales with her second husband, Robert, she gained a history degree at York and spent many years researching local history, particularly the monastic landscape of nearby Fountains Abbey, and was a co-author of several books. Elizabeth has organised archaeological tours to places such as Pompeii, Rhodes, Orkney and Shetland, as well as being a historical guide/lecturer for travel companies. She has three children and two grandchildren.
