The sibling of one’s grandmother, considered from the perspective of a grandchild, is the individual’s great-aunt. This familial relationship establishes a generational connection, typically characterized by a difference of two generations. For instance, the children of the great-aunt are related to the individual as cousins, specifically first cousins once removed.
Understanding this relationship is important for constructing accurate family trees and genealogical records. Accurate identification of family relationships facilitates legal processes involving inheritance and lineage verification. Furthermore, acknowledging extended familial bonds can contribute to a stronger sense of family identity and promote intergenerational connections.
