I have just obtained new information and have uploaded Mary
Horrocks and John
Whitehead, married 14 Sep 1796 at
Bolton, to my RootsWeb WorldConnect database, horrocks. Mary is indeed a sister to John and Samuel, the founders of
Horrocks & Co. in
Preston. Those siblings are my first cousins, 7 times removed. I'm descended from their first cousin, Henry, who operated the Stone
Mill for John and Samuel. Henry lived in
Vale House, still standing, in
Turton Bottom, near Edgworth, just north of
Bolton
