One of the best-known pipe companies, Comoys, existed long time as the distributed family business. The founding father Henry Comoy emigrated in 1879 from France to England, but the St Claude factory remained for a long time the supplier of briar and turned bowls . Soon management passed to Henry's sons who took in a share theirs cousins by the name Chapuis. Therefore the company was named Cha-Com. Yes, it's Comoy too, just a different genealogical branch.
