Henry Lines was born on February 10, 1813, in Connecticut. He lived in New Haven, Connecticut, until around 1850, when he moved to Bristol, Wisconsin. He married a woman named Susan, and they had at least four children: Henry, born around 1843; Catherine, born around 1845; Robert, born on July 15, 1848; George, born around 1853; and Rossiter, born around 1858. He worked as a farmer, and by 1850, he owned $2,000 of real estate. The family moved to Kenosha, Wisconsin, around 1850, and he worked as a harness maker there. He supported the Democratic Party until the mid-1850s, when he joined the Republican Party. In 1856, he helped organize a local “Fremont and Dayton Club.”
By 1860, he owned $1,200 of real estate and $4,000 of personal property. They moved to Oshkosh, Wisconsin, in the 1860s, and by 1870, he owned $2,200 of real estate and $100 of personal property. A local writer described him as an “active, prompt, industrious business man, and in all respects, a useful public spirited citizen.” He died in Oshkosh on December 23, 1877.
