Michael Mannix m. Mary Anne Bowler bef. 1842

Children known:
Cathrine Mannix born Clash, County Kerry 1842 emigrated to Australia and married.

Does anyone have any possible further information on this family?

Also, does anyone know the location of Clash? I looked it up but found two and don't know which one is the one I'm looking for. Where are Mannix's most common in County Kerry?
Any help would be most appreciated.

Thanks,
A. O'Brien,
