My forefather, Johannes Feuerstein emigrated from Elsass to the USA in 1750 and was the first known carrier of the name Feuerstein/Firestone to the USA. It is believed that the Feuerstein family was established in Elsass by three brothers, Johann, Theobald & Nicholas, who came from the province of Vorarlberg. I am trying to find the family lineage/connection to Vorarlberg. When they came to be in Elsass and why. I believe there may be a connection to the Barockbaumeisters who took with them young men to work as apprentices and that they then remained in Elsass. This is just a theory. Any help is welcomed.
