I have many kin in Sullivan Twp; those include Carol Ley m.Robert Lewis Auerbach in 1944.
Carol's parents were Wm Daniel & Ruby Hoffman - 6 children;
Carol's grandparents Wm Phillip & Anna Freisch - 4 children;
That's as far back as I have information quickly at hand, but Wm Phillip 1860-1940 needs a father and Michael may be a good bet.
I also have some other JeffCo references at hand which may help us - I haven't researched the Ley line completely, but might find some burial information
Have a look at http://zelltree.com/Pedigrees/2/789.htm
- if anything rings a bell I'll be happy to help.
