Am looking for any information regarding an Agnes Robertson, born 14/4/1884 somewhere in Scotland. She died 10/12/1969 in Ruislip, Hillingdon. She married my great uncle George Sturrock, although I don't know when. He was a Director of Public Works in the Straits Settlements in the 1930s (now Singapore & Malaysia). I cannot find either a birth or marriage record. All info comes from her death record and the informant was her son George Munro Sturrock.
Any help would be much appreciated.
