w/o John Haymond ===== This is not my research, nor my Hollenback family. I use it for reference so I don't "steal" a Hollenback that has already been claimed.
Mary Hollenback's parents are George Hollenback and Hannah Barton. I have done enough research on George to know that he spent some time in Berkeley Co., VA then moved on to Monongalia Co.
