Some of you may want to try "brouseing" the online IGI. Looking at their information COULD introduce some names to study... folks that MIGHT be your ancestor. To further explain... usually the parents named one of the sons after the father or after the grandfather. Try experimenting with different given names to see what you can find. You can change the settings on the online IGI to produce different results. In my most recent sleuthing, I wanted to look for all Johannes KEIMs, b. in PA between 1759 and 1799. There were lots of hits and I found some Johanneses we've never seen mentioned on this list. Sometimes you find something just by playing around with these online searches. Try it!
