I rather sure that it is not the same Lewis family, unless this John W. Lewis descended thorugh siblings of the Augusta County John Lewis, head of the Lewis clan. It was the son of the second John who established Sweet Springs resort. It's interesting to me, however, that the property of the John W. Lewis, about 2,000 acres in Allegheny County) was very near the property owned by William Lewis in Monroe County. I've seen references, from census records I believe, in which John W. is listed as having been born in both Pennsylvania and Maryland. I haven't looked at the dates, but maybe he was born in just one place (duh!), but that the place had been in both states at different times. The Mason-Dixon survey was performed to settle conflict (sometimes armed) between Maryland and Pennsylvania over disputed territory. Maybe my John W. actually was born in both Pa. and Md. I'll have to follow up on that.
