These were indeed Crown property, so copyright periods should be
calculated from creation and are unrelated to life periods. My
understanding of British IP in the 19th century, is that 14 years
would apply (I think that's right for 1891, feel free to correct me
with a source). I doubt that copyright would have been renewed by the
publisher, in fact I'm not sure that's possible for Crown works,
though if it were, then another 14 years could be added. 28 years
could then take a small number of the maps up to 1911 and into the new
copyright act, giving them 50 years from creation date.

However you would calculate it, they are definitely copyright expired
more than 80 years ago, and mostly beyond having 100 years of public
domain status. Getting the best template on the Commons image page, is
perhaps something to investigate longer term with a bit of
housekeeping intelligently based on dates, especially if the copyright
calculation takes us beyond 1923 so that the US copyright part needs
adjusting. I'm not in a rush to improve that bit, compared to getting
the full set up on Commons first.

Thanks for highlighting it,
