For anyone interested in learing more about DNA Testing for Genealogical Purposes, you might like to read the article that appeared in the Boston Globe about our family project. Since the article appeared, my first cousin, Lester Van Glennon, also matches the three men mentioned in the article, proving that we are all family. It is very difficult to trace lineage in Ireland as there are few remaining records after the destruction by fire of records in Dublin during the Anglo-Irish War. There has been much correspondence between many different Glennon/Glennan families in the U.S. and in County Roscommon, Ireland, and we were all thinking that we had to be related, but there were just no records to prove it. Now DNA testing has made it a certainty that we are "cousins". Most genealogist whose ancestors came from what is now the Republic of Ireland and were Catholics can not trace back any further than the 1840s. DNA Testing is offering a way for people to at least determine kinship. I think you will find the article interesting. There are several more Glennon men to be tested, and we are looking forward to the results. http://www.boston.com/dailyglobe2/175/focus/We_are_family+.shtml
