McInerneys/Starrs/Hellberts of Castletown

~~Hello,
I am searching for any information regarding the McInerney family of Castletownarra in North Tipperary.

There is a family grave at Castletown church besides Lough Derg which states, Erected by Thady McInerney in memory of Patrick McInerney who departed this life 1820 aged 60 years.

I believe this Thady to be the brother or uncle of Patrick McInerney 1801-1889 who married Bridget Starr (b.c.1810). They had children together, including Patrick (b. 1839 my g-g-grandfather) Timothy and Thomas (b. 1851). They held land at Laghtea.
In 1825 in the Tithe Applotment books a McKenertney held 18 acres at Loughtea (i.e. Laghtea) with a Hellebert. There are no forenames given.

The above is a general outline of the family. I am interested in any information whatsoever. In 1849 one Mary McInerney went to Australia as a famine orphan, her mother being Margaret [OMeara possibly] and father Timothy McInerney. She sailed on the Caroline Eliza ship bound for Williamstown, Australia. I believe her to my a cousin to my g-g-grandfather Patrick (.b.1833-1911).
Any information relating to any of the above or in relation to the families of Starr or Hellebert would be appreciated.

Regards,

Luke McInerney
