The following book review was written by Bobbi King:
Mr. Dobson gathered the 17th-century names of “ordinary people” whose roots were native to Ireland, or who were immigrant English, with a few names of Huguenot and Dutch immigrants. These collected names can be used to identify locations of families during the 1600s. Those persons of Scottish origin are collected in Mr. Dobson’s Scots-Irish Links, 1575-1725, and are not included in the People of Ireland works.
Mr. Dobson writes that there are few church baptism, marriage, and burial records from the Irish Catholic parishes before the mid-1750s. Presbyterian church records date from the 1670s, and the Quakers maintained records from the 1650s. As the predominant religion, the missing Catholic records represent a significant amount of missing data. Mr. Dobson accessed a considerable amount of material not available to the ordinary researcher, along with primary sources such as governmental records and references found in Irish, British, and European sources.
