I have Van Sickle's in W.Maryland and Somerset Co., PA(Ursina).My grandmother was Ethel P. Van Sickle. Her father was William Ellsworth and his father Isaac H. Van Sickel.They lived in Selbysport, Garrett Co, MD until a dam flooded there town and they moved to Ursina, Somerset Co., PA about 10 miles north of their town in MD.Isaac's father was David(Louis,Zachariah, Samuel).I heard they decend from the Gravesend, NY family which were from Ghent, Netherlands.Isaac served in the Civil War for the Union. He is buried in Ursina as well as Wm E.Isaac's father David is from a farm half in Preston Co, W.V. and half in Garrett Co,MD (north of Friendsville, MD).David is supposed to be buried on his farm that has since been plowed over. I would like to compare what you have and give you what you might need that I have.
