According to Denver Assessor records, 2210 Williams Street was built in 1898. No building permit could be located to confirm this date, but the first owner, William M. Welsh, appears in the 1899 Denver city directory at this address. William M. Welsh was born in 1858 in Ohio and married Emma Kelly in Missouri in 1890. The couple was in Denver by 1897. City directories show that William worked as a manufacturer’s agent. William and Emma lived at 2210 Williams until selling the home to Edward and Lucy Jenner in 1925.
