Historians of eighteenth-century Ireland agree in stating that catholics succeeded in amassing considerable wealth in trade, in spite of, or even because of, the popery laws, but little effort has been made to examine this question in detail.
What percentage of the principal merchants and traders of Ireland belonged to the catholic faith, or what percentage of the trade of Ireland was in their hands during the century? It is doubtful whether these questions will ever be answered completely. Contemporary travel books, and even contemporary local histories such as those of Charles Smith, scarcely mention trade, and contribute not at all to solving our particular problem. Local histories of more modern date concentrate on political rather than on economic history; and although it is to be hoped that local historians and genealogists will fill in some of the gaps, from family papers, from local newspapers and other available sources, the general historian investigating the problem has at present no regional or local studies to assist him in his researches. He must therefore try to piece together such scraps of information as are available and endeavour to arrive at some general conclusions.
