Family trees can be confusing especially when you start getting into extended family members. It’s difficult to remember how different people in your family are related to one another. You might be wondering “What is your mom’s cousin to me?” How about your mom’s cousin’s child? And then there’s the prickly issue of what to call these people when you get into relatives who are once or twice removed.

Don’t worry; we’re here to help break it down.

What is my mom’s cousin to me?

Outside your immediate family, you encounter relations such as a “second cousin” or “first cousin once removed.” These terms are pretty ambiguous, so it’s understandable to be confused.

To begin with, your mom’s cousin is your first cousin once removed (see below). If your mom’s cousin has children, those children will be your second cousins. That is to say, your second cousins are the children of your first cousin once removed.

What does once removed mean?

Cousins from different generations are said to be removed. It’s similar to how “great” and “grand” denotes generations between you and your great grandmother. If you have any first cousins in your family, their children will be your first cousins once removed. They are “removed” by being a generation younger.

If your mom’s cousin has a child, that child is actually your second cousin. Because you share great grandparents, you’re both in the same generation.

What do I call my mother’s cousin?

Your mother’s cousin may be your “first cousin once removed,” but that is really just a fun bit of trivia. Most people don’t call their mom’s cousin that. Instead, most families refer to these relations as aunts and uncles.

That’s understandable when you have nieces and nephews already calling you “aunt so-and-so.” Young children take a while to understand different relationships. It can take a few years to understand that their parents also have parents, brothers and sisters. It’s easier to let all the kids call you the same thing than to single out your cousin’s children and ask them to call you something else.

For that reason, you may already call your mom’s cousins aunt and uncle. There’s no need to change that, but it’s also perfectly fine to call them “cousin.” If you met them as an adult, it may feel more appropriate to refer to them as “cousin so-and-so.”


Now you can easily keep track of family relations, including all your different kinds of cousins. Just remember that removed refers to generations and things become easier to break down.
