I wasn't saying it was the product of a scriptorium. I was saying that many businesses and many things created in the Middle Ages were family affairs. Lauber is only one of a zillion examples of a "family affair" business. Trade secrets and guild memberships were critical to survival in those days and if you had a family member who was already a member, you had a better chance of getting in. It was difficult to go off somewhere else and be accepted. Some people even lost the rights of local citizenship if they left a village for any period of time.
These were the days of walled cities.
