Hi Roberta, I'm sorry I can't help you on the Cornelius & Mary Tunison line. They are not inmy line of Tunisons, although I do have two Cornelius's in my line. My Great Great grandfather was Cornelius Walter and married Dinah Walker, and my great geandfather was Cornelius Walter Jr., and he married three times but none to a Mary. However we do connect on Richead Heath and Sarah Wilson. Richard was a son of the Immigrant Andrew Heath and wes born in the late 1690's or early 1700's. There seems to be no dates for the birth of Richard or his brothers or sisters but they were all baptized together about 1704. Richard married Sarah Wilson 6 Nov 1736. Sarah's parents were Samuel Wilson Sr. & Esther Overton. After Sarah's death Richard married a Mary____. I have him having only one child and that would be Esther. Esther married Abraham Coryell and they had eleven Children: Sarah, Agnes, David, Elsie, Susannah, Ann, Esther, Abraham, Richard, John, and Elias/Eltas. I have more on Richard if you would like the info and also on the descendents of his father Andrew. My mother and several people she became aquainted with while doing research on the Heaths put together a manuscript," The Heath Family of Hunterdon County, New Jersey". The date on it is April 1977 but the research was done in the sixties and seventies. Don
