Harrington family Muintervarra early 1800`s

Searching for info/ townlands/ surviving descendants/ any info at all regards to Patrick Harrington born/ baptised in "Muinterverra " (where?) on 19th March 1825.............father John Harrington (grandfather Timothy Harrington) and mother Catherine (Hurley/Hurly) .............later .Patrick married Catharine Lyons (from St Finbarr`s Cork City) in London in about 1850 
~~(Lyons family==Shandon??)................their daughter Mary was my great grandmother and she married a quarryman from Clee Hill, Ludlow called Walter Head........there is a book written about Walter and his times endorsed by Dennis Skinner MP ! But the info in it only gives 1861 census info that Patrick and Catharine with two daughters Catherine and Mary Ann are "sleeping in a shed on the estate" ! Fruit picking--they lived all their lives in Hereford and Ludlow (nice towns !) But I want to go and se where they originated from etc.

Have been searching for decades (due to father`s adoption after Walter junior denied being his real father and enlisted into Royal Artillery in 1915.)............need a bit more help from local experts now 

thanks in hope
