Sir Arthur Blennerhassett, 3rd Baronet

The Catholic marriage of the (future) 3rd Baronet, 26 August 1826, Killorglin RC par records.
I do not know what is in front of Arthur's name. It is maybe some version of "Dominus" for "Sir". Except he had not yet become "Sir Arthur".

Arthur might be "A. Blennerhasset, J.P." who approved George Cashel joining the County Constabulary 1828.
