Joyce - Yes, the children of 1st cousins are second cousins to each other - and 1st cousins once removed to their parents' 1st cousins. Their children will be third cousins - and 2nd cousins once removed from their parents' second cousins - and 1st cousins twice removed from their grandparents' 1st cousins! Here's an explanation from About.com at http://genealogy.about.com/library/tips/blcousins.htm: "First cousins are the people in your family who have two of the same grandparents as you. Second cousins have the same great-grandparents as you, but not the same grandparents. Third cousins have in common two great-great-grandparents and their ancestors. "When cousins descend from common ancestors by a different number of generations they are called 'removed.' "Once removed means there is a difference of one generation. Your mother's first cousin would be your first cousin, once removed. She is one generation younger than your grandparents and you are two generations younger than your grandparents. Twice removed means that there is a two-generation difference. Your grandmother's first cousin would be your first cousin, twice removed because you are separated by two generations. Just to complicate matters, there are also many cases of double cousins. This situation usually occurs when siblings from one family marry siblings from another family. The resulting children, grandchildren, etc. are double cousins, because they share all four ancestors in common." As to what constitutes "kissin' cousins", that's another topic. My simple understanding was that meant cousins lawfully allowed to marry - second & more distant cousins when I learned it. But which cousins are allowed to marriage is covered extensively at http://www.cousincouples.com/?page=states. Robert
