Dolly and Minerva are pretty well bound up within the confines of Ackermann's Repository. It's not so bad, since there is such a wide variety of information to be found in each month's issue. Just cast an eye at this table of contents for the January 1812 issue. Something for everyone!
However, Mother has had other influences, having married into a branch of the Ackermann family from some as-yet unknown publication. Her knowledge is sometimes a bit unsettling for the girls.
