Hi, I doubt this would help, but I thought I'd pass it along.......it's probably not the same name.
We have the name 'BUBBS'and'BUBS' in our family back in 1850's to ????....One was a John BUBBS, b.1808(?) Died abt.1862-John was a civil war hero, and had approx 10 children that at least the youngest half, have the name BUBS.
You mentioned a small town inPA between Pittsburg and Erie- These BUBBS/BUBS lived in Rochester PA.
For the 1860 fed census, they are listed in Virginia, but they came back to Rochester PA by 1870.
Rochester is in Beaver County, PA.
