Arthur Charles Roe was the son baptised in St. John the Evangelist CoE, Kilburn, on 8 June 1873 for parents Daniel Samuel Roe, a purveyor of horse flesh, and Harriet Clara Toms, the family can be seen in various censuses from 1881 onwards in the Deptford area of London, there's a family tree on the 'Ancestry' website (my usual caveat about potential inaccuracy applies), Arthur had a number of siblings including a brother Stanley Bernard Roe, who placed the following notice in a 1914 issue of the 'Era' (which was largely a theatrical journal), confirming Arthur's alternative surname:
WANTED, Arthur C. Ashton - Roe's address, by STANLEY B. ROE. Communicate immediately, C/o W. Paxton, 6 Arklow-Road, New Cross, S.E.There are only a few newspaper references to Arthur Ashton as an actor/singer, including one in 1900 (Wicklow) about him suing a drama company that had engaged both him and his wife.
