Siegfried I, Count of Sponheim

[1][2] Likewise Siegfried had a family relationship of unknown degree with Count Stephan I of Sponheim (d. ca.

1080), patriarch of the Rhenish branch of the Sponheim dynasty, which survives as the present-day Princes of Sayn-Wittgenstein.

In his attendance was Count Siegfried as his close companion,[3] who thus arrived from Rhenish Franconia in the southeastern estates of the German kingdom.

Siegfried married Richgard, the heiress of Count Engelbert IV in the Puster Valley from the Carinthian family of the Sieghardinger[1] and Aribonids.

The Hungarian March was finally dissolved and incorporated under the rule of the Babenberg margrave Ernest of Austria from 1055.
