Today’s blog introduces the last of the major new features from the recent update of dynastree. As announced, the Kekulé-number is now displayed in every profile. So, what does it stand for?

This internationally accepted system describes the ancestral relations through numbers. The progenitor is assigned the number one, while the male descendants are assigned ascending even numbers, and ascending odd numbers are assigned to the female descendants. Dynastree now features this numbering system – the corresponding number can be seen on every profile. The Kekulé-number is also known as Ahnentafel (German for ancestor table), and as the Eytzinger Method, Sosa Method, and Sosa-Stradonitz Method.
