In an article on the prestigious families of Bologna and their palaces mention is made of a building which was at one time known as the Franchini House. Here’s an excerpt from that page:
The Ricci-Curbastro House, in ancient times the Franchini House (Via San Vitale, 31). It is carried out in elegant 16th century architecture. The terracottas in the three windows of the unfinished part next to the small turret were added in 1902.
My husband’s grandfather always said that our branch of the Franchinis was related to the Franchinis of Bologna who were part of the minor nobility – although we haven’t substantiated this connection as of yet!
