Amazing find, Trish, how did you come across Shape? Anyway, between your find and your effort, Ruskie, I am now sure I have a firm sighting of Mary Pywell's lot and, in particular, Susanne's link to Samuel. Thanks to both of you for that!
In answer to your question, Ruskie, identifying Samuel's parents is a bit of a lottery - from different sources, he is variously listed as being born in Leicestershire, Lincolnshire, and Northampton, so I am still hunting.
But, again, thanks for you help with Mary P.
