second cousin
Shared great-grandparent connection
A second cousin is a relative who shares great-grandparents with you but not grandparents—specifically, the child of your parent's first cousin.
The relationship is more distant than first cousins, who share grandparents.
I barely know my second cousins—we only meet at family reunions.
The term is often confused with "first cousin once removed," which describes a generational difference rather than lateral distance.
