Margaret Mulcahy born 1844

Hi My great grandmother Margaret Mucahy daughter of John Mulcahy and Margaret Desmond was born in March 1844. John was a farmer in Gurannes and married Margaret Desmond on the 17th Feb 1840 in the parish of  Murragh & Templemartin. They had 6 other children that I know of - William b1840, John 1842, Humphrey 1846, Mary 1849, Catherine 1859 & Ansty 1854. 

Margaret married a farmer Timothy Murphy in  RC Chapel Knockavilla, Innishannon, Co Cork, on 18th June 1871.  They lived on his farm in Ballyhesty Co Cork and had at least 6 daughters. 

Is anyone else researching this Mulcahy family?  Any suggestions as to where her parents John and Margaret might be buried?
