Thank you for your reply.
Since my message, I found the Ethell history on the web and can see the relationship now - Richard Lancelot Ethell, born 1861 in Malton.
Sophia Sarah Ethell's marriage is not in the history. She married George Russell in Gillingham in 1864 and had seven children: -
William George RUSSELL 1865
Sarah Alice RUSSELL 1866
Friend Thomas RUSSELL 1871
Albert Charles RUSSELL 1873
Rosanna Sophia RUSSELL 1879
Emily Ellen RUSSELL 1883
Willie Edward RUSSELL 1886
