Jim, Philip Lavely Jr. was born in Maryland to Philip Sr. They sold all there goods in 1800 and moved to West Moreland PA. They are in the census of 1800 but moved right after that. Most of the PA line came out of Philip, however there is a David Lavely in the census of 1860 for Pittsburg that is listed as coming from Ireland. The birth of Daniel in Somerset works with the dates that I have information on.
There were 4 Major moves for the Lavely's from Maryland, 1 to Kentucky then Indiana, I to Tenn., 1 to Iowa, and 1 to Pennsylvania.
Please use my email address and I will be glad to tell you what I have.
