Background:

In the 1970s we knew:  Probate, in the year 1939 Admons.:

"SWEETMAN Georgina Elizabeth of 42 Chichester-Road Kilburn Middlesex, Widow, died 13 June 1939. Administration London 3 August to Rosa Elizabeth Wilson (wife of Clement Sydney Wilson). £486 18s 4d.
To  Rose Elizabeth Wilson, 15 Worton Way Hounslow, Lawful niece of the whole blood and one of the persons entitled to share in the estate of the said intestate.
Filed by:  Mssrs. Sidney Smith Son & Leefe,  42 Kilburn High Road  NW6"

    So we figured that if Rose or Rosa Elizabeth Wilson was a full niece (lawful of the whole blood) she would have to be a daughter of a brother or sister, of Georgina Elizabeth Foulger (henceforth GEF).   If Rose or Rosa was a daughter of a brother of GEF her maiden name would be Foulger so we can look for a marriage of Rose or Rosa Elizabeth Foulger to Clement Sydney Wilson.  However we couldn't find any brother of GEF.   If Rose or Rosa was the daughter of a sister, she could have any maiden name, but her mother's maiden name would still have to be Foulger. Also the name Wiskin poped up as a possibility so she might have been Rose or Rosa Elizabeth Wiskin.  The background continues here and details all the marriages of Clement Wilsons from 1900 to 1939.  It is fascinating to see how we started trying to figure things out and how very close we were without stumbling on the right answer!

    The answer came out of the blue thanks to Brian Foulger - see his web site at http://www.brianfoulgerfamilyhistory.co.uk/

    It turns out that Rosa Wilson was a niece Georgina Elizabeth Foulger - being Rosa Mathias, the daughter of GEF's sister Rosa Maria Foulger who had married Thomas Mathias.  Thomas Wisken (yes Wisken, not Wiskin!) was GEF's cousin, Harriet Foulger's husband. 

    In the index for DQ 1898 Clarence (sic) Sidney Wilson and Rose (sic) Elizabeth Mathias married in Brentford (3a 175)

    In 1881 we see the family at 122 Marylebone Road (RG11/0157/57/38): Thomas and Rosa Mathias and daughters Ada H. age 3 (born JQ 1878 in index as Ada Harriet Mathias Marylebone 1a 532)  and Rosa Elizabeth Mathias age 5m (born DQ 1880 in index as Rosa E. Mathian Marylebone 1a 596)

    In 1901 we see Clement (22) and Rosa (21) Wilson and daughter Elsie (Elsie Ada Wilson DQ 1898 Brentford 3a 88).
