Thanks to Jonathan Billings for sending in this picture. This is L.C. Billings (Jonathan's Great Grandfather) and his son, Warren (Jonathan's Great Uncle). The picture is dated 1900. The picture appears to have been taken at the Billings residence on Summer Street. There is a picture of the Billings house in the 'Milford Homes' section of this web site that also shows some of the Billings family.
