Query about address

[sagehen]

If we may take Jane Austen's usage as representative, it would appear that
among the gentry, at the end of the XVIII, beginning of the XIX Cent, the
eldest unmarried daughter would be styled Miss Surname, while her younger
sisters  would be Miss Given Name.  Collectively, they would be the Misses
Surname; this latter, a usage which was still in order in my childhood, at
least, in the Midwest of the Thirties.
