In my last post, I neglected to give you some information that might interest you. I may be in the Porterfield Book; I don't have it. James (1777-1861), Alexander (b.1780) and John (1783-1871) were sons of William(?) Porterfield (b. c1751), a tenant on the Abercorn Estate, Ballylennon, County Donegal, Ireland. Mary Robb (1776??-1858) and Margaret Robb (1790-1871) were daughters of John Robband Monica Dunlap of Drumore Twp and Carlisle, PA. I believe all the above are interred in or around Warnock Cemetery, Smith Township, Belmont County. Any additional or contrary information is welcome.
