From at least March 1850 William Quilliam of Arbory was described as a landed proprietor of Arronac (either the name of his property or a locality within Ronague, Arbory). He died in 1878 and in the 1881 census the property is noted as having passed to his widow, Ann. I would like to know how I can locate exact details of where this property was, when William obtained the property and who owned it previously.
Any help with sources or information would be appreciated.
