All the articles are described as "about women" by ODNB themselves.
James Barry is generally considered a woman, her motivation for assuming
male identity is presumed to be the desire to practice medicine. Women
historically have passed as men to join male-exclusive professions,
though one might imagine the successes were usually undocumented.
The red crosses are to be be used as the items are found, confirmed to
be the same person, and the information from the ODNB article is used in
the Wikipedia article. Clearly this is something where the OBIN will be
fantastically useful for.
The forename, name, nickname, married name, etc. fields are for the
template to construct whatever alternative article names or redirects
are needed. Human names are complex, those of the British upper
classes, doubly so, though at least they use mainly the basic Latin
alphabet.
The list is sufficiently long that it would need to be split, presumably
by letter, to avoid exceeding the transclude limits.
Thanks for your many and various comments, I hope that covers the queries.
Richard.
