I am also looking for more info on James Irvin Hoge and Margaret St. Clair. Unfortunately, all I have at present is what little I've gleaned from the census and from other's board postings. I have James I. Hoge as the son of James and Mary (Irvin) Hoge.
I have James and Margaret as the parents of Archibald, born about 1818, and also Martha, Thomas, Elizabeth, Sarah and John I. As has often been decried regarding some of my Pope ancestors, "further particulars are wanting". Will be happy to correspond.
