I have found records that Jacob Isenberger was the son of Jacob E Isenberger, he was born in 1790 in PA. Jacobs mother was Ana Eva Imig, born 1856 in Germany and died 1938 in Illinois. My maiden name is Isenberger. My father was Claude born in 1899 and died in 1963. Let me know if this helps and if you have any other info. I would like to find how the Isenbergers got to PA and where they came from.
