Good work and advice Jan
Dearly love to help with this one so checked back further in 1939
Olive J Porter (added later to the document married name Botterill) dob 26/6/1924, was employed as a nursery maid by George D Jeffreys (retired army) who also employed a further 9 servants address Burkham House Alton rural district Hampshire.
William J Botterill (only 2 listed this the more likely) dob 14/11/1913 Manager Window cleaning business and his sister Barbara June Botterill dob 4/10/1915 (later added married name EDWARDS) living at 370 Goldhawk road Hammersmith London.
Do your partner or her sister recall an aunty Barbara???
Do you have a copy of the marriage cert at all if not then would suggest getting a copy to ensure a start point. I feel sure there is a chance together we can solve this one. As Jan has said it will be important to trace birth certificate for Caroline Ann that she has listed. The birth was registered in December qtr 1946 this would cover Oct/Nov/Dec of that year, Olives Marriage was registered March Qtr 1947, covering Jan/Feb/March so at the most only 6 months between birth and marriage.
