She was mentioned in her father's will in 1779 as being the wife of Wm Daily.
Was Mary really only 13 when she and William married?
From the McCubbins Collection of Rowan Co, NC:
"The will of Mary Dealy who died 14 November 1819 was unwritten, but on 21 November 1819, James Briggs and Hannah Briggs say that she left John Dealy a purse with $1.44, a small pot,a sheep, a bell which are at the house of (son-in-law) Alexander Stephens and left the balance to Alexander Stephens and his wife Mary. Probated in February 1820."
