Their source was Hutchins (History and Antiquities of Dorset) and info. from Mr Bengt Nilsson. The English side appear's accurate. (the parish records record their deaths and there is a huge memorial with dates in Milton Abbey)
I haven't the resources or knowledge to check the Swedish birth date or parentage. The biography says that his father was supervisor at the 'packhouse'. What was that? I'm sure that my google results of flat pack timber houses and ikea aren't quite right!
