Looking for Jordan of Virginia

My Great-grandmother was Sarah Sylvesta JORDAN. She was born in Fulton City, Illinois and married John S. HILSINGER. Her parents were Daniel JORDAN and Saphrona THAYER. Daniel was born in Guernsey Co. Ohio; his parents were Adam JORDAN and Ludema WALLER. Adam was born in Goshen, Belmont Co. Ohio; his parents were Joshua JORDAN and Susannah EVANS. I have the names of Joshua's children (including those from his second marriage), but I cannot find his parents. Any information is appreciated.
