Genealogy Tools for Family Relationships

Use a focused family relationship calculator to name the connection between two people when you know their shared ancestor.

# Name the Relationship Between Two People

Start with the shared ancestor already identified in your family tree. Count the parent links from each person up to that ancestor, then use the calculator to distinguish a direct relationship, siblings, first cousins, or cousins separated by different generations.

# Read a Family Relationship Path

The useful answer is the relationship name, not the raw total. For example, 1 + 1 means both people are children of the same ancestor, so they are siblings. 2 + 2 means both are grandchildren of that ancestor, so they are first cousins. 2 + 3 keeps the first cousin relationship but adds one generation of removal.

# A Focused Tool with Clear Limits

This category currently contains one tool for classifying a known family path. It does not search archives, infer an unknown ancestor, verify documents, identify living people, or decide inheritance. Use original records and the rules of the relevant jurisdiction when the relationship has legal or official consequences.
