The tools serious genealogists rely on.

AncestorOS is built around the Genealogical Proof Standard — so your research holds up under scrutiny.

Research Logs

Track every research session with structured logs: the objective, the repositories visited, the sources examined, the results found, and your conclusions. The paper trail that defends your work.

Evidence Explained Citations

Templates for all major source types — vital records, census, military, land, church, and more — formatted to Elizabeth Shown Mills' Evidence Explained standard, the gold standard for genealogical citation.

GPS Source Quality Ratings

Rate the reliability of each source using the Genealogical Proof Standard framework — original vs. derivative, primary vs. secondary, direct vs. indirect. Know how much weight each piece of evidence carries.

Document Vault

Upload scans of certificates, letters, photos, military records, and any other documents. Organize by client or family line, and link documents directly to citations and research log entries.

Frequently Asked
