It was his work on the New York State Canal System from 1849 through 1856 that brought him to Seneca Falls, New York. There he married in the summer of 1855 Angeline Chamberlain (died 1901), daughter of Congressman Jacob P. Chamberlain. The couple had five sons, the last surviving of whom was Charles Chamberlain Johnson. The Johnson residence still stands on Cayuga Street in Seneca Falls, and is being developed into condominiums after years as a home for women.
