In doing my own checking I did find a very large Charles W Barrack family living in Westmoreland county next to a couple Inscoe's one a child of our George. I found Martha with 3 kids in 1870 living next door to her mother no husband. John was living with an Edmonds in 1900 before he married. Keep up the good detective work.
Going to Stanford Medical Center on 5th and 6th then off to So Cal for a few days so email me direct if you find more.
