There were a lot of Gillespies in Cecil County MD where they settled in early 1700's. They arrived in this area along with Ewings, Porters and a few of my family (Polks). There was a strong Scotch-Irish community in the Octoraro, Nottingham and Rising Sun areas. Some are found in Cecil County to this day and others moved on to PA and Va, etc. I don't have a good reference for this, but you should contact the Cecil County Historical Society.
