Lewis Smith was born around 1806 in Connecticut. He married a woman named Abigail, and they had at least four children: Elizabeth, born around 1830; Mary, born around 1832; Martha, born around 1834; and Miles, born around 1838. They lived in Milford, Connecticut, and he earned a living as a farmer. By 1850, he owned $1,000 of real estate. A decade later, he owned $3,000 of real estate and $200 of personal property. He probably died in the 1860s.
