There were a lot of Nourishs in the area especially at that time. The records are a little patchy as many of them were non-Conformists. It is an uncommon name and it is highly likely they are all connected. Unfortunately, I haven't come across a Pentalow connection and I don't have a record of Fanny Nourish. To my knowledge, I am the only one researching the Nourish family but I will be back in touch should I make the connection. Sorry not to be of any help.
