You are welcome,
Charles & Bertha MIDLANE could have a daughter named Gwendoline born 1911 - you would need to check 1911 cenus.
On FreeBMD there's a 1911 Bertha G MIDLANE also daughter 1912 Freda M MIDLANE, 1918 Edward J MIDLANE with mmn JAMES
regarding the death of Frank JAMES, who I persume is Bertha's brother, Bertha Louise JAMES was born Jun q 1889 Cardiff.
Do you have the James family on the 1891 & 1901 census as this could give you a clue as to when Frank JAMES was born
