How are John Adams Jr. and Abigail Smith Adams third cousins?

I've been researching but I can't find any sort of connection between them.

Apparently, the definition of third cousin is the child of your second cousin, who is your parent's cousin.

Does anyone know how John Adams and his wife, Abigail Adams are third cousins?

Thanks in advance

    You only had two things wrong.

    1) John Adams SENIOR married his third cousin, Abagail Smith.

    2) Your 2nd cousins are the CHILDREN of your parents' first cousins.

    Your parents' first cousins are your first cousins once removed.

    Your third cousins are the children of your parents' second cousins.

    You are confused. Third cousins have one set of great great grandparents in common, as their closest common ancestors.
