I would also love to find this book Vonnie. My husband is descended from Robert Johnston b. abt. 1775, emigrated from Ireland about 1790, had among his descendants a son William married to Susan Harbaugh, and a grandson John Aaron Johnston married to Mary Ellen Brown. These are my husband's Johnston ancestors. While I don't know anything about this book, I do have lists of Robert Johnston's descendants. Let me know if this is your family.
