The DNA Detectives TV show didn't help much at all. And it would probably not have used DNA to track down a great-uncle buried near Athens.

Of more importance is that we have established a lineage from Jacinda to Charlemagne ("Father of Europe"). Not the lineage Geni.com gives her, because that appears to run through a childless person. See Hawise de Guines (c958-1015) for the final link created in our chain.
