I spent some time at Westminster Archives today without much success. Also at the Probate Office to find that neither Nathaniel made a will.
However, all is redeemed by a visit to the Islington Cemetery in Finchley.
The entries of burials are in large ledgers, one for each year. They are in alphabetical order then in month order, finally in order of burial. There are no exact dates.
February 1911
Name: Bryceson Nathaniel; No. 138957; Abode (!) Royal Free Hospital; Class of grave, 3; Block V2 Grave 1229P
Pretty sure this is the son as the register says he died in Islington & the RFH was there then.
March 1911
Name Bryceson Nathaniel; No. 139239; Abode, Dempsey St, Stepney; Class 2; V2; 1229P
This must be our man as he is said to have died in Mile end Reg. district & that would be right. Same grave you notice. I will take some photos to show that that area of the cemetery is a jungle and it will be impossible to find the grave even if a stone exists[/i].
Dempsey St no longer exists. The luftwaffe made a lot of alterations in that area in the 1940s
