Hi Ewan
If you mean for to ask MNH to look at the listings for you, i am sure i did that for you up to 1919 a while back, the search works this way,
We go and sign in and fill in a request form, they take it away to another room, bring the book/s to you and you search, While the staff are very helpful they just dont have time to search, I may have this wrong if i do im sure someone will explain better than me, buti did search for you and nothing is comming up , only the alice cox in 1911, if she is the person you still seek,,
