Jacqueline, My Dad had a Great Uncle George, who would fit the timeframe you presented. There are several large branches of the Shuster family that can found in the Westmoreland County History Books, in Westmoreland County, PA. Some of these Shusters offspring moved on to Ohio, Indiana and other locations west, north and south. I would recommend checking the Westmoreland County history.
If you would like to contact me about this, please feel free to do so.
