Hello, The Glass's had quite a presence in Pope County and there is a lot of them. In a series of Books called the Saga of Southern Illinois you will find most of the Glass's that you are looking for. I am directly related to a Dudley Glass first found in Livingston Ky in 1799 then moving to Pope County. He had lots of kids, one being Elizabeth Glass who is one of my great ggg grandmothers. My mother knows lots on the Glass family, her address in zitalindell@juno.com. Feel free to E-mail her, genealogy is her hobby. Jim
