At Historigen, we specialize in traditional genealogy research, adoptee parent identification using DNA, verifying family myths, and locating ancestors’ final resting places.

Whether you’re searching for long-lost family connections, validating family legends, or building a solid foundation for your lineage, Historigen is here to guide and support you every step of the way. Our DNA research has identified birth parents, confirmed grandparents, and united half-siblings. We are passionate about providing verifiable information to confirm family relationships.

Our volunteer work has helped law enforcement and local officials across the country identify unknown remains and provide information to families of missing persons. We believe everyone deserves a name and a connection to family.
