The family history chart illustrated below will sort you out if, like plenty of others, you've ever wondered about second cousin or 'removed' cousins. Working out the relationships between your ancestors is a key part of genealogy, so keep the form handy after you've printed it.
You might also like to use the chart to work through the real-life example below of second cousins and 'once removed' cousins. You start the process by finding the common ancestor of two individuals.
In the tree, Eamonn Doyle and Betty Driscoll are first cousins once removed. They were born in the same year, but there are two generations between Eamonn and Patrick Doyle, and three generations between Betty Driscoll and Patrick Doyle.
The terms 'once removed' and 'twice removed' occur when the generations between two individuals and a common ancestor are unequal in number. Fortunately, you don't have to remember a mathematical formula or learn these family relationships by heart.
Just click the image above to download and start sorting out your first and second cousins from 'removed' relationships.
When you've printed it, keep a copy handy so that you can quickly calculate the relationship between two ancestors in your family tree, or between you and one of your Irish ancestors.
