Relationship Calculator

Calculating relationships based on shared autosomal DNA centimorgans (cM) helps users understand familial connections. The spreadsheet includes a reference chart detailing degrees of separation for various relationships, such as grandparents, aunts, uncles, and cousins. Users can input shared cM values to highlight potential relationships, with ranges provided for each connection. The data is derived from the Shared cM Project, offering insights into genetic genealogy. Additional tabs provide templates and examples for specific family trees, enhancing usability for genealogists.
