Case Study 3

DRM's situation was a little different. He'd been adopted, but he already knew who his biological parents were — he wasn't searching for anyone. What he wanted to know was far more specific: was he genetically connected to a particular family line?

That's an important distinction. DNA research isn't always about identifying an unknown parent — sometimes it's about testing whether the evidence supports a connection you already suspect.

DRM had five potentially relevant matches, sharing between roughly 90 and 179 cM — useful, but none strong enough on its own to answer his question. They needed to be looked at as a group.

I used the Leeds Method to sort his matches into family groups and focused in on the relevant paternal lines. From there, it was a case of trawling through match after match — working through each one's profile, their tree where one existed, their shared matches, and the families that kept turning up among those connections. Rather than hunting for one specific person, I was looking for a pattern. Eventually, the surname at the heart of DRM's question began appearing consistently, again and again, across the matches in the relevant group.

No single match answered his question. It was the pattern that emerged from working through so many of them — the same family name surfacing repeatedly across separate matches — that confirmed it: DRM was genuinely connected to the family line he'd asked about.

What this case shows: the biggest match isn't always the one that matters, and the answer doesn't always come from building an elaborate tree. Sometimes it's methodical, patient work — trawling through match after match until a pattern emerges that no single one of them could show you on its own. It's exactly why I like to see a potential client's match list before deciding whether a case is workable.
