Thanks Kathleen, Ellen and Samuel were married in London in 1904. Ellen's father T P Mullins was an army chaplain and I guess he moved from his native Ireland to England in around about 1870. He and his wife appear in the 1881 Census in Kent. Samuel listed his occupation as Surveyor on the marriage certificate and was resident in Dublin.
Ellen's siblings were Annie, Beatrice, Thomas, Patrick and Ethel.
The 1911 census you refer to shows Samuel and Ellen after they had married and moved to Dublin. Of the children, the 2 year old Bernard Samuel is my wife's grandfather.
