A lineage - and a Statistic


Omitting the last generations for privacy of concerned. But also, because I want to be sure, sure, sure that all given ages are from pre-Industrial times - the ones reputed to have a mean life expectancy of 40. Well, at least not if you discount child and youth mortality, which is obviously the case in any lineage, since only adults procreate:
