We live near Peterborough. My email is
rogers.roundhills@virgin.net. I believe Archibald died in 1918. Lydia was an insulin dependent diabetic but lived into her eighties. I have some data - Eg. I just located and received the Metropolitan Police pension details for John Tumath - Archibald and Lydia's grandfather. The attached photo shows Lydia and Frank with their three children (one being my mother on Lydia's knee) around 1920.
