Liz - I just found your note. This is partially my line. My 6G grandparents were John & Ruth (----) Peacock. My line continues with Jonathan & Mable (Robinson), James & Anna Gertrude (Finkle), then Jonathan & Hannah (Sharp), Elizabeth Jane Peacock marr Dr Moses Braddock Alter, and then on down to me.
I visited Yorkshire in 2000 and was lucky to find the Ackworth School still in existance. The people were very friendly there and brought out the original documents signed by Jonathan (husb of Mable Robinson) in 1795 when his son James (my 4G Grdfa) enrolled. Two other brothers of James attended also (Jonathan & William)
James and Mabel & 6 of their children came to NY in 1802 on certificate from a Quaker Mtg in Scarborough York.
I found a lot of info on a film "Yorkshire Quaker Minutes" Film MR L33. I believe this is a Mormon film number.
