As the marriage record shows that Josiah and Lydia married in 1900, and the photograph seemed to date from perhaps the 1870s, the expert photodating analysis of Jayne Shrimpton was sought, who deduced that the photo dates from c.1876-1882. The proximity of this date to the inferred marriage date of 1874 (see the 1911 Census entry for Josiah and Lydia) only serves to thicken the plot.
