scroll down on the left and there is a pdf file labeled the Gregson family
This family connects only Waaaaaaayyyyyyy back, at #7 above, Arthur Gregorysonne. But there is some very good research in the first few pages.
Reid, who compiled the above 3 pages, references the "32 typed pages" of The History of The Gregson Family of Whalley, Lancashire. This is available on ancestry, if you have subscriptions that includes England. Fortunately, I had access and was able to download all the pages - which are actually 64, although only 32 are numbered. (every other page is not numbered) I've compiled them into a pdf file - email me and I'll gladly send it to you, especially if you are willing to help me interpret it all and sort it all out! :-)
