John L Smith is listed in Middletown, Connecticut in 1850 as a jeweler. He was born in Ireland in about 1797. I didn't try to trace his career. E R Spear & Co was Edward R Spear's business in Rockland, Maine which apparently began in 1854. Initially the family were book and stationary merchants. http://books.google.com/books?id=iABCAA ... &q&f=false
