J.C. Brown (Johnathan Clark Brown, Jr.) was born in 1807, and died in 1872. He had various business partners from 1832 until 1842 when he bought out Wm. Hills, and formed J.C. Brown & Co. He used both his own name and Forestville Mfg. Co. on the labels.
From 1847-1855 he conducted business without partners as the Forestville Manufacturing Company or the Forrestville Clock Manufactory.
Brown’s business failed in 1855, and he was bought out by E.N. Welch. The J.C. Brown factory became part of the E.N. Welch clock manufacturing complex.
