Your Thomas Hartung (md Mary Faust) was the son of Samuel Hartung (bd 29 Oct 1813, dd 12 Jun 1887) md to Abigail Bennighoff (bd 23 Sept 1813, dd 17 Nov, yr?). Thomas was one of 9 children: Christian, John, Gideon, Thomas, David, William, Caroline, Mary, Alvena.
In the 1850 Schuykill County, PA census, Samuel (age 35) and Abby (age 34) were living with Samuel's parents, Michael Hartung (62) and Maria (Ann Maria Billman)(53) and Samuel and Abby's 7 (at that time anyway) children (ages 2-13). I tell you a little more at email@example.com. I am descended from Samuel's brother, David Hartung, but I got the info on Samuel's line from one of your cousins. E-mail me if you want to contact her too.
