The Fundatio Monasterii Sancti Pauli in Carinthia names "comes Engelbertus ex patre Sigfrido Francorum civis, ex matre Rihkarda maiorum Karinthia primus", and in a later passage names "Sifridi natale solum Spanheimmense fuerat castrum, Richkart Laventinis oriunda" as parents of "Hartwic Magdeburgensis archiepiscopus".
Wegener assumes that she was Richgard, daughter of Engelbert Graf im Inn- und Norital [Sieghardinger] & his wife Liutgard --- because she named her son Engelbert. However, the same reasoning could apply to any other contemporary member of the Sieghardinger family, in which the name Engelbert was commonly used.
The necrology of Salzburg St Rudpert records the death "VII Id Jul" of "Rihkart com". The brothers Graf Engelbert and Hartwig Archbishop of Magdeburg transferred the remains of their mother Richgard from Spanheim to St Paul to be next to her husband Graf Siegfried, the document dated [1100] confirming that their father died while returning from pilgrimage to Jerusalem and was first buried in Bulgaria and that their mother died while on pilgrimage to Santiago de Compostela. 1
