If you take your year of birth and subtract 25 years for each generation you go back, you can find an approximate year that someone was born. The big event in Ireland was the Potato famine, which triggered a lot of immigration. I like to study history of a country before tackling geneolgy questions. I search for names of places for a persons name to help me guess where the most likely place someone is from. Street names and names of rivers, creeks, and other places can be found through searches. There are many search engines available. If you need futher help, then ask questions through this forum. There are many people willing to help. Obviously you have the ability to discover many things, since you were able to find this web site. Good luck Bob Lyles Mississippi, USA
