My ancestor was Francis Ignatius Ricarde-Seaver and either Dona Maria or Marie Antoinette. Their daughter, Catherine Ricard married Patrick Prendergast in Athy. Their daughter, Mary Ann born 1858 , came to Aust where she married Patrick lambert, in Maryborough, Q'land, in 1882. This may be of some interest. The Prendergasts owned the mill in Athy.
