Edie, In the "Genealogical Landmarks and Milestones...." by Ralph L. Johnson & David H. Bergey, MD, repub. 1992, there is a footnote on the page 59 (Children of Henry Hallman), on Child No. 8. Jacob, b. June 12, 1757, d. Apr 20, 1823. Lived on his father's farm which he bought in 1795 for 100 lb. Footnote (1) Deed Book 28, page 546. If you could find that deed, it might give you some information. I believe the farm was near Norristown, is that correct? Faith
