Hi
Thank your for the information for the burial from Deceased online in Reply 6.  

From the index, looks to have Richard Chandler, burial date 23 February 1922 in Merton
as well as the following:
Chandler Percy 
Burial date 24 June 1911 
Location Merton 
Chandler Phyllis 
Burial date 14 April 1917 
Location Merton 
Chandler Thomas 
Burial date 05 March 1917 
Location Merton 
This information I think fits with the information on Percy in reply 7.
The other deaths I think fit with the children that die young in 1917. 

Deaths Mar 1917
Chandler    Thomas C    4    Croydon    2a   676
Deaths Jun 1917 
CHANDLER    Phyllis M    3    Croydon    2a   546
If the 1921 female birth in on 1939 register Free search with Phoebe, does that mean that this person has died?
Any further thoughts most welcome.
Helen
