Hi all, This is just a reminder to Armstrong County researchers about changing county lines and the formation of counties. This is a situation I often forget about so I thought I maybe should mention it to others. Be careful when you find a family that was in Westmoreland County make a move to Armstrong County. On March 12, 1800, a considerable chunk of Westmoreland became Armstrong County. I have families that did make a physical move from the former to the latter but I also have families whose address changed without a move. And there are a lot of other cases with other counties that are similar. Just something to keep in mind. Jim
