If someone walked up to you and said "Hello, I'm your third cousin, twice removed,"
would you have any idea what they meant? Most people have a good understanding of basic relationship words such as "mother,"
"father," "aunt," "uncle," "brother," and "sister." But what about the relationship terms that we don't use in everyday speech?
Terms like "second cousin" and "first cousin, once removed"? We don't tend to speak about our relationships in such exact
terms ("cousin" seems good enough when you are introducing one person to another), so most of us aren't familiar with what
these words mean.
Sometimes, especially when working on your family history, it's handy to know how to
describe your family relationships more exactly. The definitions below should help you get your bearings!
(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 and uncles.
Your second cousins are the people
in your family who have the same great-grandparents as you., but not the same grandparents.
Fourth, and Fifth Cousins
Your third cousins have the same
great-great-grandparents, fourth cousins have the same great-great-great-grandparents, and 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
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 and 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
and your grandmother's first cousin are first cousins, twice removed.
