No.. it is not. She is your first cousin, once (one generation) removed. Your children would be 2nd cousins to her.
Age is not relevant here. With large families, a brother might be 20 yrs older than the baby of the family, but still remains his brother. The "once removed" stuff comes in to count how many generations away from the common ancestor you are.
siblings share parents.
cousins share grandparents
2nd cousins share the same gr grand parents
and so forth...

edit.
you stated your aunt is her grandmother. someone does NOT READ, and goes on to say your aunt is your great aunt.
sheeesh

Yes, if your relative is your 1st cousin's daughter, then that daughter is your 2nd cousin.

I'd say that she would be your second cousin.

If your first cousin has a child, then that child would be your second cousin!
I know......I have alot of them!
Just like if your second cousin has a child,. then that child would be your 3rd cousin......ect...and so on!!

yes she's your second cousin

Actually, Wendy C. is correct. You are GENEALOGICALLY 1st cousins once removed. No doubt.

You also have a Civil relationship of "V" and a Cannon relationship of 3.

However, familially it would not be uncommon for a family to claim 2nd cousin status....in typical family references, things like once removed are not used....just as the husband of your aunt would familialy be your Uncle though genealogically he is just the husband of your aunt - no relation.

Addendum: HOW TO FIGURE IT OUT

For any two people, find the common ancestor. In this case, the common ancestor is the asker's grandparents. The person who is CLOSEST to that common ancestor establishes the "cousin number" And that is the number of generations SEPARATING that closest person from the common ancestor. In this case, there is 1 generation separating the asker from the common relative - so the two people are 1st cousins.

NOW, figure out the number of generations separating the second person from the common relative - in this case, there are two generations separating the cousin's daughter (the cousin and the aunt). The "removed" is the difference between the separations (two generations - one generation = 1 times removed or once removed).

Note that if we were talking about the asker and her cousin, both are 1 generation separated (1st cousins) and 1 generation - 1 generation - 0 times removed or just 1st cousins.

that's your cuz

Wendy is right and deserves the best answer. A lot of people don't understand the removes. They think you go back 1st, 2nd, 3rd irregardless of what generation a person is. If you are in the same generation coming down from a common ancestor there are no removes.

Your first cousins children are your first cousins once removed. Your first cousins children and your children are 2nd cousins since they are in the same generation coming down from a common ancestor.

Her mother is your first cousin, so she would be your second cousin. Age doesn't matter (I am 59 and have a 2nd cousin who is only 22; and among my nieces and nephews, their cousins range in age from 34 years to 2 months--including the 2nd cousins among them). Oh, her grandmother is your GREAT-aunt because your grandmother and her grandmother are sisters. There is a family relationship chart at http://freepages.genealogy.rootsweb.com/... .
It is for the family of Bob Wise, but the chart about midways down the page shows how to figure out who's related to whom and how many times removed.

She is your 1st cousin, once removed. Your child and her child would be 2nd cousins.

yes

it is your 1st cousin once removed.

If you had a child, that child would be 2nd cousins to her, because they are on the same family level.
