Donnchadh Rua Mac Con Mara (1715-1810)

He  

When he did return to Ireland, he travelled around the countryside as a schoolmaster, the fate of the 'spoilt priest', as they called his like in those days.  Canon Power described him as a wayward, wandering son of genius.  He was appointed assistant master at the famous classical school at Seskinane, Touraneena, Co. Waterford, in 1741 and he taught there for some years afterwards.  This school opened its doors in the first half of the 18th century, the moment the vigour of the Penal Laws commenced to relax. He was well-known in Sliabh gCua—the district around the Knockmealdown Mountains and the hilly land between Dungarvan and Clonmel. In 1743 he was reported as having travelled on a fishing boat to Newfoundland. It is said that he did so to escape the wrath of a family whose daughter he had made pregnant.

On a reputed second voyage to Newfoundland or Talamh an Éisc (the land of Fish), as they all called it, he wrote a long poem, Eachtra Giolla an Amaráin (The adventures of an unfortunate man).  It was written under peculiar circumstances.  Donnchadh announced his intention of going to Newfoundland and a collection was speedily made up for him, as well as a supply of foodstuffs for the voyage - remember, at that time the voyage would take several weeks.  Our brave poet duly arrived in Waterford, from which port he was due to sail but, instead of boarding his ship, he commenced to make merry in some local tavern until his passage money was exhausted.  After this he sold his supply of foodstuffs and, having accounted in like manner with the proceeds of the sale, he faced back again to the parish of Newcastle.  To the queries put to him he replied, jocosely, that he had been to Newfoundland and, a short time afterwards, he wrote a poem of 360 verses in which he described his voyage.  The poem describes how the ship was attacked by a French frigate and a fight ensues in which our poet is the hero.  The emigrant ship is captured but, through the strategy of Donnchadh the frigate is overpowered and the emigrant ship returns in safety once more to Waterford. He was a wild person. His conduct was said to have led to expulsion from the seminary, his first voyage to Newfoundland, and now to more trouble with the Roman Catholic church.     

This time he became a member of the Church of Ireland in Rossmire, Newtown near Kilmacthomas (see picture, on left). He was appointed church clerk but when the Church of Ireland clergy, and people, discovered how great a rogue was their new convert, he was dismissed, so he crawled back to Catholicism once more.

He was a happy-go-lucky, reckless individual who was ever welcome to wedding or christening, where he sang songs and joked, singing the praises of some and satirising others with all the acerbic wit of a gaelic poet. Mac Con Mara's escapades, poems and songs were part of the folklore in County Waterford but died with the Irish language.  In 1810, at the age of 95, he died in Newtown, where he had been a temporary Protestant and is buried in the Catholic cemetery there. The inscription over his grave in Latin gives the necessary details and also at the end of the text:
 
If whatever sins he committed have been wiped out by penance, give him, oh Lord eternal rest in the true motherland.  

The old rogue could have appreciated the unintended humour of this conditional blessing on his spirit. Needless to remark he wrote a repentance poem, as every Gaelic poet did, before his final departure from where he had enjoyed himself and given pleasure to others.
