I am searching for emigrant ancestor to America, John Ogg, and wife Mary; they came from Scotland, in July, 1752, settling in Virginia. John had brother Alexander who also came to Virginia. John's wife Mary, or his mother may have been a Sinclair. Also searching for McChristys (various spellings). Ancestor Arthur McChristy was born ca. 1735, possibly in Scotland; he came to America and was living in Fayette Co., Pennsylvania as early as 1762.
