6 degrees of Separation?

During the COVID isolation phase there seemed to be a fashion of people issuing challenges to delve into personal histories for a number of days to follow a theme.   I’m not going to do a multi-day epic but instead will (after some preamble) write about links with 10 people with whom I have 1 or 2 degrees of separation.
