Brian, Thanks for the message. Unfortunately the 1841 census is not indexed so searching it takes weeks. When I went through it just for my own local area in Bolton it took about 2 months of weekly visits to the local library looking for the Longworths. Sorry, but I don't have the time available to do it all over again for the Barlows - and there are a lot more Barlows than Longworths in Bolton! Maybe you should check if anyone is doing a one-name study on the Barlow family, or is researching the name in Lancashire. Hope you manage to find someone to help you. Best wishes.Vera.
