DNA Match Guide

A practical starting point for DNA matches who want to connect a shared cM result to the documented family archive.

Curated public kit and ancestor-line data only. This page does not geocode, import, or automatically infer relationships from GEDCOM data.

Evidence caution

Shared cM can suggest a range of possible relationships, but it does not prove a specific ancestor by itself. Use the results below as a research path, then confirm the connection with shared matches, places, surnames, and documentary evidence.

DNA match guide

Start with the kit you matched

Choose the matching kit, add the shared cM amount, and use the suggested ancestor range as a starting point for documentary research.

1. Which kit did you match?

2. Shared cM with that kit

3. Where did you test?

Possible common ancestors

Enter a shared cM amount to show a candidate range.

What to send the archive

This guide needs JavaScript to filter the curated kit and cM ranges. The DNA data itself is static and does not use an outside service.
