In 1911 she looks like staying with a family, whose son she married seven years later, at The Birches, the Common, Weybridge, Surrey:

Dorothy Evelyn had her surname misspelled from Tunnard and her birth place from Malay Straits.

No Taylor births found with a Tunnard mother’s maiden name from 1918 to 1938.

In 1939 my surmise that Dorothy married a son of the above house is confirmed by the presence of Ethel Frances, very likely the sister of her husband, in her married residence at Hawthorns Churchfields Avenue, Weybridge, Surrey:

First name(s)  Last name(s)  Birth date  Sex  Occupation  Marital status  Schedule  Schedule sub number
Ethel F    Taylor   11 Jul 1877  F  Independent Means          Single   48  1
Clement B  Taylor   10 Dec 1884  M  Oil Distribution Engineer  Married  48  2
Dorothy E  Taylor   02 Aug 1883  F  Unpaid Domestic Duties     Married  48  3
Eva M      Collins  13 Nov 1877  F  Independent Means          Single   48  4

Her probate index:

1973
TAYLOR, Dorothy Evelyn, of Lovely Cottage 171 Woodham La New Hae Weybridge Sy died 25 April 1973  Probate Winchester 23 August £12022  733306590K

Ordered as she was the last of her line from Powys and she may have left a bit to some distant relatives.
____________________

In her will dated 17th Dec 1968 she appointed as executors her solicitors Messrs Guillaume & sons, her husband Clement Bramley, Taylor and Patricia Mary Higgins.  Her husband did not serve as her executor.

She also listed:

1. Mrs Gladys Louise Elliott
2. Mrs Mary Barter,
3. Mrs Eleanor Mary Banks

and the residue of her estate after her husband’s death was to go to the survivors of:

1. Mrs Patricia mary Higgins,
2. Her godson Captain John Devereux Treacher RN
3. Barbara Mary Greenhalgh

I cannot see that any of these were relatives.  So no action.
