Well, Paul, what can I say ... if
Miss Audrey Harris isn't the alleged dedicatee, nor the obvious candidate (as it earlier seemed), and if there's another possible/plausible dedicatee in the vicinity, active in the same Era ... your guess is as good as mine!
My post #1 was simply trusting/following what was earlier told in the dear old
HBW Alive Key (the very basis for that certain claim is all unknown to me). I believed I was just adding a missing Death year.
Neither she, nor this bird, are included in my MS, thus I haven't checked it (nor the dedicatee herself) in any serious depth (basically, not deeper than what's been shown in this thread).
However, I don't think I can reach much further in this topic.
Good luck finding the truth!
Björn
PS. Though, I cannot help wondering where Jobling found her originally ...
PPS. This far, until proven otherwise, I'd keep my bet on
Miss Harris.
