My web site, located at http://www.geocities.com/geojenkhttp://www.geocities.com/geojenk has a very extensive collection of Genealogical Biographies of people and families that were located in or about McKeesport, Pa from it's inception. Also on the site are Genealogical Biographies and pictures of thousands of others that lived or passed through the Western Pennsylvania, USA area.
My web site is FREE and exists to help researchers find info on their families. I also am not trying to sell anything!!!
I also have quite a collection of photos of McKeesport and other areas. Give the site a try..it is a very large site!!!
