Hi Elaine , Jean has given you some good information. Had a look on UK FreeBmd for the death of Catherine Kelly in England, 1906-1960 and only two Catherine P's , one aged 1 and the other March Qtr aged 58 in Godstone , Surrey.
There are a stack of Margaret A's but these are likelys
Sep Q 1908 43 Preston
Dec Q 1938 76 Liverpool North
Jun Q 1939 75 Manchester.
That is assuming they did not marry.
Upper Norwood seems to be part of London.
Saw your postings on The Peerage , did Annie Dunn remarry after the death at sea of George ?
Is Charles George death age 14 . 1871 , Kingston UK his death ?
Cheers
David Dwyer
