A charter dated to [1050/55] records that the church of Craon was founded by "Suhardus Vetulus…Guarini filii eius", that "Suhardus junior frater eius" succeeded after the death of Guérin, and names "Guarinus cognomina Bastardus, Suhardi…Vetuli filius".
The name of Guérin’s wife is not known. The name Maurice, given to her grandson, suggests the possibility of a family connection with Maurice d’Anjou (son of Geoffroy I “Grisegonelle” Comte d’Anjou by his second marriage), given how unusual this name appears to have been at the time. 1
