Would someone please check an exact date of birth in the 1939 register? Using the index only, there are only two individuals named William Penn with a birth date in 1880, one in Staffordshire and one in Hendon, Mdx. At the Hendon address there is also a Rosa Penn, born 1879.
A William Penn & Rosa Johnson were married June quarter 1933, Bethnal G. 1c 242
so aged about 53-54. A possible second marriage.
Possible death registration for William aged 61, Hackney 1b 327 DecQ 1942
(while the Staffs. one apparently died 1947, registered at Stoke)
