The following tables contain all the references to persons with the surname Flack that I have found who were likely living in Ireland prior to 1850. These records are a composite from a number of different sources (indicated in the table). The first table is sorted on the Estimated date of Birth to facilitate locating persons with known or estimated dates of birth. The estimated has been calculated using the reported date of the record, minus the stated age of the person listed and could therefore be inaccurate by +or- 2 years.
Following the All Ireland tables, are three additional sets of tables in which the tables have been sorted by County, Parish/Barony and by Townland in the hope that this will reveal family groups in each of Cavan, Monaghan, Armagh and Fermanagh.
