I found this document this morning by accident and noted immediately the inclusion of Wolfe Tone in 1787 but there are other well-known families in the list. The lists on the site date from 1501 to 1944. By searching for Kildare the first reference I found was 1629 though the information in the early years is scant and a more exhaustive troll of the list would be necessary.
9 July 1629 ARTHUR WHITE, second son of Nicholas W , of Lexlipp, County Kildare, Ireland, knight.
