 Nothing is known of Agatha's early life, and what speculation has appeared is inextricably linked to the contentious issue of Agatha's paternity, one of the unresolved questions of medieval genealogy.As the birth of her children is speculatively placed at around the year 1045, her own birth was probably before about 1030.She came to England with her husband and children in 1057, but was widowed shortly after her arrival.
