This morning, I received the Administration of Estate for Alan Brown, grandson to Annie. Alan died July 15,1957 in Crumpsall Hospital, Manchester. His estate was administered in 1958 and the only person mentioned was his widow Pamela Jane nee Marsden who remarried to Miles Powell Hinchliffe in 1961. Pamela Jane died Aug 29, 2015 in Scotland but I don't know what took her there, as Miles died 2014 in Poulton-le-Fylde, Lancashire.
I looked for John Edward's will in 1959 on gov.uk but didn't find one that year or in several years following. His widow Frances nee Lee/Leigh formerly Thornhill lived until Aug 17, 1996. I don't know if they had children and thought the will might reveal that.
So I am still waiting for the marriage record of Annie Brown to George Marsden in 1917 which is to be mailed Dec 18 but might take a couple weeks after that to get to me in Canada.
