👉 Nongeologial, also known as a non-geological or non-historical family tree, refers to a family tree that does not follow any specific lineage or historical sequence. It can be based on unrelated individuals or events, and it is often used in the context of genealogy or family history research. Nongeologial families are often considered more detailed and comprehensive than other types of family trees, as they provide a more complete picture of the relationships between individuals within the family.
