There were several Christopher George in Census and on find-a-grave in Cambria County. The George family was large with many sons, grandsons, etc. and names repeated. But the Christopher of interest here was 32 in 1870, 44 and identified as Christopher C George in 1880 and so I believe he was the son age 13 with his parents Philip and Rebecca in 1850.

Age 32 in 1870, Mary is 31, Francis is 1.

In 1880, he is Christopher C George age 44, Mary M is 32 (really?) and Francis is 11.
