The family tree is a bit older than that with Jurix involved. There is a
reasonable family tree chart on the internet, but I'm not sure its 100%
accurate - then again memory of things that long ago can be misleading so
it may be me. SuSE is I think also older than Red Hat.

Bogus kind of led to both Debian and Red Hat but I believe Debian is a
bit older. There are several other older distributions still such as
Slackware. The oldest "Linux distribution" was probably MCC 0.95+ which
migrated its users to Debian as one of its updates and ceased to exist
long ago.
