Extremely cool. I'm into genealogy and can trace my family 10 generations back (250 years) to their arrival to Argentina. Documentation is lost or lacking once you reach Europe, other branches of the family with more recent arrivals to the country are very hard to trace. In part due to mismatching surnames and in part due to the wars.

We have started asking old family members to send us whatsapp audios with tales and things they remember from long-passed away family members; and what was life like in the 1930-40-50s. I want to start organizing all the info and data we have, my father has built a couple family trees, but this wiki format is indeed very promising. I'll keep an eye on this and see if we can use it.
