I have been researching my fathers' family, who lived in Whitechurch from at least 1826 onwards till sometime between 1880 to 1901. They then moved closer to the Cork city.
The website with parish records for Whitechurch is www.rootsireland.ie
. The only draw-back, is there is a charge for it. Whitechurch comes under the Parish of Blarney.https://www.familysearch.org/
is a very good site which is being updated very often. It has a great range of records.
Griffiths land evualation site http://www.nli.ie/en/griffiths-valuation.aspx
is a good one.
I hope this helps.
