There was a Donovan chemist shop on Main st Portlaoise in years gone by, and I went to school (in years gone by!) with a Paddy Donovan.
Came across this from Patients received into Queens County Infirmary, Maryborough 1824/25.
March 1st 1824, admitted for Venereal, Judith Donovan, discharged, 27/3/1824
