Many from Chester & Delaware cntys, PA moved to the Berkeley cnty, WV area. I happen to have all the SELLARS/SELLER/SELLERS wills from FTM CD # 209 Pennsylvania Wills 1682-1834 pulled and into a file. If you think there is a chance that your SELLERS came from that area of PA I'd be happy to send the wills file on to you. Samuel was a common given name amongst the SELLERS in that area of PA.
