I saw the posting about the mill of Joesph Hollingsworth, late 1700's of Frederick Co.. I have ancestry through Isaac Hollingsworth (I believe he's the brother to the Joseph you refer to as the owner of the mill) Til your posting i knew nothing of a woollen mill operation. If this is the same family parents of Joseph Hollingsworth are George Hollingsworth and Hannah Mc Kay of Hopewell. Hope someone reading this is interested in the genealogical data of this family as well as the historical and business venture. Appreciate your posting. Would love to know more about the Hollingsworth family and/or their business.Thanks, Jacquelyn Martin eldridgemartin@msn.com
