Melissa's relationship with the Reisinger family is included in Doug Reisinger's book, "The Reisinger Family: Descendants of Peter Reisinger" that was released in 1999. In addition to the five children you list, there was also Guy, Mary Ellen, Margaret L. Joseph Jacob and Nellie Marie. Thomas Jefferson (Edgar) Reisinger is a brother of my great-grandfather. There is more on Melissa's ancestry included in Gregg Jacobs' recent publication, "The Descendants of Peter Jacobs." I think both of these publications will help you greatly in your search on behalf of your friend. Rita [Snyder] Chatham
