Cousins are people who share a common ancestor that is at least two generations away, such as a grandparent or great-grandparent. As per the following family tree chart, a "once removed" cousin is a generation above or below the concerned person. For example, your father's first cousin (your uncle or aunt) is your first cousin, but she is "once removed" because there is a generation between you and them. Another example of a first cousin once removed would be the child of your first cousin. With the help of EdrawMax, you can easily create a first cousin once removed chart to understand the heritage history.
