He was probably related to the Danish royal family, as "Hemming" was one of their favoured names.
He probably soon returned to Francia, since there is no evidence of him in Danish politics after he and his brothers were driven out by the sons of Godfrid in 813.
[2] It is probable that Hemming was received by the Franks and granted Walcheren, a fortress in Frisia, as a benefice.
If so, Hemming appears to have been the superior, since Thegan of Trier in his Gesta Hludowici imperatoris, an account of the reign of Louis the Pious, names him first when recording the dead, followed by "another leader, Eccihard, and many of the emperor's nobles".
[4] On the other hand, Hemming may have been a courtier sent by the emperor to aid the local leader, Eccihard.
