Tim, Does that mean that the first structure in Lewisville was in Chester or Cecil county. I am not familiar with that area although I did travel there a few years ago. I did go by and see the new Rock Church and visited Head of Christiana, but could not find any grave for my David Alexander of New Munster.(b.circa1680-died c.1740) Some material stated that he moved to Chester County and died there and I am of the belief that it is possible that the Mason/Dixon line changed the picture. Are you at all familiar with the graveyard connected with the Rock Church? Helen
