If somebody said, “ I'm your third cousin, twice removed," would you have any idea what they means? No me neither!
We all have a good understanding of basic relationship words such as "mother," "father," "aunt," "uncle," "brother," "sister", "cousin" etc.
But do we know much about "second cousin" & "first cousin, once removed"?
Cousin" usually seems good enough when you are introducing one person to another, so most of us aren't familiar with what these words mean.
The definitions below should help you out.
Cousin (a.k.a "first cousin"):
Your first cousins are the people in your family who have two of the same grandparents as you. In other words, they are the children of your aunts & uncles.
Your second cousins are the people in your family who have the same great-grandparents as you, but not the same grandparents.
Third, Fourth, & Fifth Cousins:
Your third cousins have the same great-great-grandparents, fourth cousins have the same great-great-great-grandparents, & so on.
: When the word "removed" is used to describe a relationship, it indicates that the two people are from different generations. You and your first cousins are in the same generation (two generations younger than your grandparents), so the word "removed" is not used to describe your relationship.
The words "once removed" mean that there is a difference of one generation.
For example, your mother's first cousin is your first cousin, once removed.
This is because your mother's first cousin is one generation younger than your grandparents & you are two generations younger than your grandparents.
This one-generation difference equals "once removed."
Twice removed means that there is a two-generation difference.
You are two generations younger than a first cousin of your grandmother, so you & your grandmother's first cousin are first cousins, twice removed.
Still confused? You’re not the only one!
Luckily I have a great chart here to make things a bit easier.
Instructions for Using a Relationship Chart
Pick two people in your family and figure out which ancestor they have in common.
For example, if you chose yourself and a cousin, you would have a grandparent in common.
Look at the top row of the chart and find the first person's relationship to the common ancestor.
Look at the far left column of the chart and find the second person's relationship to the common ancestor.
Determine where the row and column containing those two relationships meet.
There are two other charts further down the page that you may wish to use.
Here are some great examples;
