Registration for Apothecaries commenced around 1790 and continued until c 1972 when the new regime took effect.
In Slater’s Directory for 1824Mary Maybury, Main Street, is listed as a dealer in drugs. She may have been in business before registration took effect but she is the first woman I have come across in this capacity.
Susanna Williams, Main Street, 1825, Kanturk is listed as an Apothecary.
If Maybury is her maiden name she may be from Kerry where the Mayburys were prominent in Kenmare/Killarney and related to the Protestant Mahonys of Dromore castle..
