| Parents | Great-grandparents |
| Uncles and Aunts | Great-granduncles and great-grandaunts |
| Siblings | Granduncles and grandaunts |

The terms "granduncle/aunt" and "great-uncle/aunt" are often used interchangeably in popular parlance, and even major genealogical sites have different usages. The usage on this site corresponds to that used by Ancestry.com. With apologies to Great-Uncle Bulgaria, the sibling of a grandparent is a granduncle, not a great-uncle, and a great-granduncle is the sibling of a great-grandparent. "Grand" attaches to the relationship it qualifies, but "great" is always joined to it by a hyphen.
