The surnames found in this article are from the Dublin city franchise roll, 1468-1512, ed. Colm Lennon and James Murray (Dublin: Dublin Corporation, 1998). This source is a collection of documents in Latin and English; while the editors unfortunately modernized all the given names, "the spelling of the surname in this edition is identical to the spelling given in the roll" (xxix). I have collected the surnames and ordered them by frequency.
These men and women in these rolls were all being admitted as free citizens of Dublin. Most were apprentices to a citizen; some married citizens and were thus eligible for citizenship; and some were children of gentry. You were also eligible to become a free citizen by paying a certain fee. The men and women in these documents were by and large English; in fact, one man who was made a citizen later had his citizenship struck out because he was "of the Irish nation" (FOOTNOTE). However, there are a couple of surnames which are clearly anglicizations of Gaelic bynames; I have marked these, and, when known, offered the standard Gaelic form for this time.
Roughly 32 citizens were entered each year for the 44 year period covered here, for a total of 1424 people; the free citizens made up a small minority of the population, which at this time was 6,000 to 8,000 (xv). At this times, surnames were by and large inherited (passed down from father to child), but women did not generally take their husband's surname upon marriage.
