   Introduction      Property      Rocklawn, Clash, Co.Tipperary
Clash, Ballymackey, Co.Tipperary
home farm of the Blennerhassett/Hassett family of Clash

Little is known of the origin of this branch of the family.
First recorded is John Hassett of Rocklawn (born c1803, where?who married on 11-Aug-1864 (aged 61) at
Templederry, Co.Tipperary (Church of Ireland), to Sarah Jane Markby of Templederry (aged 19), perhaps as his 2nd wife.
John died 30-Oct-1899, Sarah Jane died 1932 - both at Rocklawn, both buried in the family plot at Culliwane Burial Ground.

The civil marriage record names him John Hassett, not Blennerhassett, but family tradition among some descendants strongly supports the view that he is descended from Blennerhassett;
this is also the belief of the Clarke family, who hold the neighbouring farm at Knockane, Toomevera, although other descendants have doubts and the Blennerhassett ancestry is not proven.

Before this marriage John Hassett lived with a brother (perhaps Timothy Hassett b.c1815, d.1865 Nenagh ?).

His wife Sarah Jane Markby is believed related to another Sarah Markby of Co.Tipperary (b.c1882 d.1964)
who in 1905 married Joseph Blennerhassett of Blackbriar (Skagduve), Co.Kerry

Following the death of Richard "Dickie" Hassett (b.1920 d.1973) Rocklawn was sold, out of the Hassett family,
to John Grace of Kilnafinch, Toomevara. Unoccupied since that time, the farmhouse is a ruin.
