Halfcousins

Half-cousins are individuals who share one grandparent in common. This relationship is a result of one parent being a full sibling to the other parent. For example, if Person A and Person B are siblings, and Person A is married to Person C, then Person B and Person C are half-cousins. Similarly, if Person A and Person B are siblings, and Person A has a child with Person D, then Person B and the child of Person A and Person D are half-cousins.

Half-cousins are not as closely related as full cousins, who share two grandparents. However, they are more closely related than half siblings, who share only one biological parent. The term "half-cousin" can also refer to a cousin who shares only one grandparent, but this usage is less common and can be confusing.

Half-cousins are not legally recognized as a specific type of relationship in many jurisdictions, but they are an important part of family dynamics and genealogy. They may share certain traits or characteristics due to their shared grandparent, but these similarities are not as pronounced as those between full siblings or full cousins.
