An extended family is a family unit that includes more than just the nuclear family, such as grandparents, aunts, uncles, and cousins. This type of family structure is often referred to as a clan, which is a group of people related by blood or marriage. CLANS are typically associated with a common ancestor, and members of the same clan often share a common surname. Extended families are found in many cultures around the world, and they provide a strong support system for their members.
