Hi, I may be able to help a few people here. A few years ago I was working with my Uncle, a local historian, on the Pilkington family from Horwich. My Uncle transcribed the diary of Richard Pilkington (c. late 1700's) who was a local businessman. It's a long time since I read it (and have no copy myself) but he mentions his sons William and Richard. At the time William is a doctor (he moved to St Helens and became one of the founders for Pilkington Glass after some kind of scandal). There is a copy of the diary in the reference section of Horwich Library.
I transcribed (on paper) a diary belonging to his son Richard. This Richard never married but was an important man in the town. Through this diary we find other family relatives like the Turners.
The houses where both Richards lived are still standing and the grave is in Horwich Parish Church graveyard. He is buried along with his father, also Richard and his son Richard.
I live in Horwich and have some church records (on paper)for Horwich and Rivington if I can be of help to anyone.
I also spent a lot of time trying to trace this Pilkington family to the Rivington Pilkingtons and Bishop James Pilkington who founded Rivington Grammar School in 1566.
