Rea family of Fermoy

I am researching my family,the Rea's of Fermoy.  My grandfather was Richard, his father was Thomas, and he had several brothers who lived in or near Fermoy.  I would appreciate any help in finding out about my family.  We will be visiting Fermoy in mid September.  I am writing a book on our family history, so any information would be of interest.  Thank you so much.
