I recently started what I thought would be an fairly simple project to make a list of my cousins on my father’s side. There are 29 of us. I ended up doing a family tree since I quickly discovered that a genealogy program would be the best way to enter the data. It’s been fascinated to learn more about current and past family members. I have used ancestry.com to look at records going back to the 1800’s. I hit a dead end at Ireland but I am still plugging away. The family tree is at: http://jheffernan.com/oldsite/HeffernanFamily/Heffernan/index.html
Never volunteer to do a family tree for an Irish Catholic family unless you are retired!
