Hello. I created a Facebook Group for genealogists who have 18th & 19th century American glassblowers in their trees. Since the trade was in high demand and the skills passed from father to son, the lives of Early American glassblowers were often interconnected as they crossed paths from job to job. Hopefully, using traditional research and genetic genealogy, we'll find more of those connections as we network and share information.
