A group member sent me a document off-list that discussed naming. I can't share it but the refences were mostly personal communications. Interestingly one reference lead me to
NAVSHIPS 900102. There is a copy here:

It's a contempary (1945) description of coaxial cables and connectors. No mention of Neill or Concelman but it does refer to N and BNC series as well as BN, LN and HN. Interestingly it compares the N series to "the orginal N connector". I now wonder if this original N was the "Naval" connector.
Even more interestingly it clearly describes the BN as "Baby N" (It is a small connector with threaded coupling now completely obsolete) and the BNC as an improved BN connector with improved construction giving constant impedance hence Baby N Constant-impedance.
So while the accreditation of the N and BNC designations to Neill and Concelman may have occoured later (and Bayonet N Compact) Clearly this was not the case at the time they were introduced.
Things have obviously changed over the years.
looks like a great resource and a new one to me.
