Hi List As we know that in some villages in Limerick (and Ireland) the same name and surname is very prolific. Understandably as this country is much older than USA, Canada and Australia etc.. Some of the naming patterns go back prior to Anglo-Saxon arrival. Hence some villages have nicknames for different branches of the family to distinguish them from each other, so don't be surprised if visiting without knowledge of the townland and requesting a common name you maybe asked are they the Widow Connor's? Turf Connor's? Micky Connor's or the Red Connors? etc.. also some of the nicknames go back for centuries. As a suggestion while using the Griffiths Valuations and you have three Thomas Connors in one townland, try and compare this to the Tithes and you may find that back then there was only one Thomas, so one maybe his son and the other a different line, or father, son and grandson as leases were sometimes taken out for the life of that individual which meant that it covered his family during his lifetime down to his grandson. Also the time between the Tithes and the Griffiths is enough to have had an offspring some twenty years, also it was not uncommon for a child of ten to fifteen years to be an agricultural labourer.
