    Note: Welf, Graf in Swabia, in the Foundation for Medieval Genealogy ~http://fmg.ac/Projects/MedLands/WURTTEMBERG.htm#ConradIParisdiedafter862 [See document in the Memories section] WELF [I], son of ROTHARD Graf & his wife --- (-[824/25]). Settipani names Welf [I] as son of Rothard[1754] but does not cite the primary source on which this is based. The Annalista Saxo names "de principibus Bawarorum qui fuit binomius, name et Eticho et Welfus dicebatur" who was father of Empress Judith[1755]. From the area of Metz, he moved to Bavaria. Graf in Swabia. m HEILWIG, daughter of --- (-after 17 Mar 833). Thegan's Vita Hludowici Imperatoris names "filiam Hwelfi ducis sui, qui erat de nobilissima progenie Bawariorum…Iudith…ex parte matris…Eigilwi nobilissimi generic Saxonici" as second wife of Emperor Ludwig[1756]. She was installed as Abbess of Chelles, near Paris[1757]. The Translatio S. Baltechildis records that Emperor Louis I visited Chelles “ubi...abbatissa Hegilwich genetrix Iudith imperatoris” for the transfer of St Bathilde’s body “XVI Kal Apr” 833[1758]. The date of Heilwig’s installation as abbess has not been ascertained. Presumably her appointment was due to the influence of her daughter Empress Judith. If that is correct, Heilwig became abbess after her daughter’s marriage in 819.
