To all the past McLaven Detectives

Two and half years later and I've only just found out some more information after giving up for a while.

After checking the 1911 census (Sidney himself had died in 1907) I found his wife working at Cox's Hotel, Jermyn Street in London. Her two eldest sons (this was a shocker) were a Boys Home in Kingham Oxford. My grandfather Frank was living with her sister, but I can not find the other son Laurance. i contacted Kingham Oxford who were kind enough to look through their records and this week they sent me the admission document. It gave me some really interesting information.
Sidney Frederick George McLaven worked as a night porter at the
Cecil Hotel in the Strand. (up until he was ill in Dec 1903)This was a huge hotel from the sounds of it with over 800 rooms. However I am unable to find him on either the 1901 or 1991 census. But ...if he was night porter i guess he would not be there but in bed sleeping somewhere ?
So finally i know where he worked - although I've never got any further finding his birth or anything
