Exactly! I think we all should choose a descendant connection. I'm going to choose one today. It'll take some thinking about,so i'll get back on this one. Who would you like to be a descendant of?
Interesting and tricky question, I'd have to give that quite some thought.
One difficult aspect of your question is that whoever anybody thinks of is likely to be 'judged' by today's standard. I suspect that there is barely a single figure from history, who was in any sort of position of power/influence/governence who would stand up to today's morality. 'Modern' people have an unfortunate tendency to look at the past through today's lens, which is wrong. (Caveat - some 'favourites' seem to get away with this, particulaly if they are distanced from us by sufficient time).
Even if one was to go for someone amazingly philanthropic for example, I'm pretty sure someone would be along soon afterwards to denounce them for something or other. Except of course, if the figure was sufficiently attuned to the modern thinking to make their past excusable. Besides, is going for such a philanthropist a cheat? I dunno!
