Understanding the Relationship
The brother of your great grandfather is not a direct ancestor in the parent line, so the term you use depends on your family structure and regional custom. In standard kinship language, he is the brother of one of your grandparents, making him a great-uncle (also written great uncle or granduncle). This designation applies whether he is your grandfather’s brother or your grandmother’s brother, though some families reserve great-uncle specifically for the male siblings of grandparents and use grand-aunt for females. The relationship sits two generations above your parent and one generation above your parent’s cousins, placing him in the extended family rather than the direct line. When no commonly used family nickname exists, great-uncle is the widely recognized, neutral term.
Basic Definitions and Kinship Position
To clarify the position of this relative, it helps to break down the generational path:
- You: person X
- Parent of X: child of the great-grandfather
- Grandparent of X: sibling of the great-grandfather
- Great-grandfather: parent of the grandparent
Because the great-grandfather’s brother shares the same parents as your grandparent, he is one generation above your grandparent. The standard label for that position in most English-speaking contexts is great-uncle. Colloquially, many people also say grand-uncle, and a few regional or heritage communities may use terms like greatfara or other historic variants, though these are uncommon in contemporary everyday usage. For clarity in this explanation, great-uncle is treated as the baseline term.
Great-Uncle Versus Other Relationship Labels
It is useful to distinguish the great-uncle from similar kinship terms to avoid confusion:
- Grandfather: the father of your parent; a direct ancestor.
- Great-grandfather: the father of your grandparent; two generations above you.
- Uncle: the brother of your parent or the husband of your aunt.
- Great-uncle: the brother of your grandparent, not a direct ancestor but part of the extended family.
- Family-of-origin terms: some families invent affectionate or specific labels based on personal history or cultural background, which may differ from the standard terms above.
When you are unsure which label applies, consider which generation the person sits in relative to yourself. If he is two generations above you and shares a parent with one of your grandparents, great-uncle is appropriate.
Historical and Regional Variations
Kinship terminology can vary across languages, cultures, and communities. In some traditions, distinctions are made between the brother of one’s grandfather from the mother’s side versus the father’s side, or between paternal and maternal sides. English usage tends to be more consolidated, generally grouping these relatives under great-uncle or grand-uncle. Certain older or regional expressions exist, including grandfader’s brother or terms borrowed from heritage languages, but in standard modern English family language and documentation, great-uncle is the most consistently understood and neutral choice.
Practical Guidance for Usage
When you need to refer to your great grandfather’s brother in conversation, writing, or formal contexts, you can rely on great-uncle as the clear and accurate term. If you are uncertain how a specific family refers to him, you can ask in a nonleading way or use the descriptive phrase the brother of my great grandfather until you learn the preferred name. In genealogical records, family trees, and legal documents, great-uncle is widely recognized and minimizes ambiguity. Keep in mind that nicknames and localized terms may exist within families, but for broad understanding and consistent communication, great-uncle serves as the dependable, evergreen term.

Common Questions and Clarifications
People often have follow-up questions about how this relationship fits into broader family structures. Is the great-grandfather’s brother also your great-uncle once removed? No, once removed typically refers to a difference in generational level within the same line of descent, such as a cousin who is one generation above or below you. The brother of your great-grandfather is in the same generation as your grandparent, so he is simply a great-uncle, not removed. Some wonder whether gender-specific terms like great-uncle grandpa or similar constructions are acceptable; in careful usage, great-uncle or grand-uncle is preferred to avoid confusion with actual grandparents. Others ask whether this relationship affects DNA or genetic closeness; in practical terms, you share a similar amount of DNA as you would with a grandparent’s brother, which is considerably closer than a more distant cousin but less than a grandparent.
