From A Topographical Dictionary of Ireland, 1837
TEMPLEMURRY, a parish, in the barony of TYRAWLEY, county of MAYO, and province of CONNAUGHT, 3 miles (N.) from Killala, on the road from Ballina to Lacken; containing 1868 inhabitants. It is situated on the bay of Rathfran, contiguous to the bay of Killala, into which the river here empties itself, and comprises 1200 statute acres, chiefly arable. Fairs are held at Rathfran on Aug. 25th and Nov. 11th. The harbour is fit only for small vessels, being dry at low water. The sea being smoother here than at the contiguous bar, some vessels prefer running up here as it is quite sheltered and safe from the sea swells. Sumrnerhill is the residence of T. Palmer, Esq.; and here are the ruins of the fine old house of Palmerstown. It is a vicarage, in the diocese of Killala, forming part of the union of Lacken: the rectory is appropriate to the dean and the precentor of Killala.
The tithes amount to £108, of which one-half is payable to the dean and the precentor, and the other half to the vicar.
In the R. C. divisions it is part of the union or district of Killala. Ruins exist of the fine old abbey of Rathfran, which was founded for Dominicans in the 12th century: adjoining is a burial-place still used.
