Without knowing at least a general time frame, it's pretty difficult to give any concrete answer.
I would check Larry Hillpot's excellent website and do a local search on those names.That would at least give you some starting point.Obituaries from the 20th century for parts of Bucks are relatively easily available from newspapers in Easton, Allentown, and Bethlehem. And can't forget the Intelligencer in Doylestown.
Church records for Bucks and the surrounding areas are really pretty good, especially German Reformed. Some are available on line, including Tohickon Reformed and St. John the Baptist Catholic.Any hit on one of your target names could lead you in another direction.
With all the records we may look through, it's good to remember that none were really compiled with genealogy in mind.So you're more than likely to end up looking in all sorts of strange and offbeat places.Good luck!
