I've been trying to find a Laughlin in the Allegheny County area who might be interested in trading information with me, so far without success. My Robert Laughlin first showed in the Octararo Creek, Lancaster County PA area in 1752. William Laughlin was there around the same time. I believe they were brothers. I believe I have traced William's descendents to the Washington , Allegheny and Beaver County areas.
