Quirke Family of Eglish RC Parish

I am trying to find infomration on the family of my great great grandmother, Bridget Quirke. She was born Jan 1831. She is strongly connected with and somehow related to Jane Wilson born about 1812 in Kings County (Offaly). Jane married Michael V. Molloy also of Kings County (Offaly) and also born about 1812.We have no knowledge of the Quirke family and would love to know more about them Thank you. Jane McGarvey
