Phil, Just wanted to add one more 'cousin guide' - this one has been very helpful in my research. Plus it's so simple! 1st cousins share the same grandparents. 2nd cousins share the same g-grandparents. 3rd cousins share the same gg-grandparents. 4th cousins share the same ggg-grandparents. 5th cousins share the same gggg-grandparents. And so on. Hope this helps too! Karen Keleher
