I have the following information about the father, Joseph Dungan and his family. He was born Southhampton, Bucks County, PA 13 April 1736, married Elizabeth Carrell, 5 Sept 1764 in PA and they had the following children:Josiah, bn 29 Jan 1765, Thomas, bn 9 Aug 1767, James, bn 1 June 1769, John bn 5 July 1771, Isaac bn 1777, Joseph bn 1780 and Benjamin bn 15 Oct 1782.At least the last 3, Isaac, Joseph and Benjamin were born in Bucks County, PA.
Also, Margaret Mitchell was the wife of Benjamin (brother of Joseph) and she died 22 January 1836 while Benjamin lived until Sept 1855.
In addition, the following notes were taken from a Ludington genealogy book, not in my possession, about Joseph and his family:
