Ravilious on the generation length: Rootsweb, Google: "It seems perhaps the generations are stretched somewhat; surely those generations following William the Marshal himself are extended beyond the typical, given his fathering children by Isabel de Clare between say 1190 (when aged about 44) and 1206 or later, when he was aged 60 or possibly more. If Gilbert Giffard of Domesday was born say 1060/1065, and his (conjectured) great-grandson John le Marshal (d. 1235) was born say 1065/1075, we have a range of between 105 and 115 years, yielding average generations of between 35 and 38 years - more than 'the average' of 28, but not abnormally so.".
