I am looking for any information on Gertrude Isabel Brancker (otherwise shown as Braucker/Brancken/Branken), born 1871 Severn House, Loch Promenade, Douglas (this may be the registry address) and married 6 Sep 1892 at Bradden, St Thomas, Isle of Man. Her father was Charles. Cannot find birth certificate or any census details. Thank You.
