From FindaGrave, composed by Shari S: "Per (Westphal article, see Sources below), a likely candidate for Mary's father is William Cassidy of Bourbon County. Some feel that she must be related to Jeremiah Cassidy of Washington County, son of Daniel of Nicholas County, since she named a son "Jeremiah Cassidy Hanna," their grandchildren intermarried, and she and Samuel lived in Nicholas County in 1800. Daniel does refer to a daughter Mary in his will, but it is currently unknown what became of her. Not enough is known of Daniel's age (other than he was born before 1865) to say whether he could be Mary's father. Still, he might be an uncle and Jeremiah a cousin, etc."
The abstract of Daniel's will, written in 1812, lists his children by first name ("Thomas, Jeremiah, William, Nelly, Mary"). Mary would have been married for the past 16 years at that point; it seems unlikely that she would not be called "Mary (married name)" in the will (including in the abstract).
