June 5, 1834 Horace Capron married Louisa V. Snowden daughter of the late Nicholas Snowden and Elizabeth Snowden. Louisa was raised at Montpelier, a former plantation which is today located on what is now Route 197, approximately 3.5 miles from the Laurel Museum.
The Snowden family had extensive land holdings, including land on the Patuxent River on which a small cotton factory, originally a grist mill, had been operating.
His marriage to Louisa brought Horace land to contribute to a new manufacturing venture in which he would be an owner rather than employee: The Patuxent Manufacturing Company.
The Patuxent Manufacturing Company was officially chartered by the State of Maryland in June, 1835. Its cotton mill, lands, houses, stores, machine shop and road down to the newly opened B&O Rail stop became the foundation for today's Laurel.
Horace Capron was related to most of his new partners. This was common practice in 19th C. manufacturing. Partners in the new venture included Capron, Theodore Jenkins, his brother-in-law, (married to Juliana Snowden), mother-in-law Elizabeth Snowden, O.C. Tiffany (a first cousin of Horace Capron), A.E. Hall, and W.C. Shaw. Deeds for property and stock for the new venture were signed by Jenkins, Capron, Osmond Tiffany and Comfort Tiffany, also Capron cousins, who were involved in a variety of Mill ventures in Maryland. Osmond Tiffany's son George P. Tiffany was mill superintendent from 1857-1877.
