Richgard (Lavant) von Sponheim (abt. 1020 - aft. 1064)

Siegfried married Richgard, the heiress of Count Engelbert IV in the Puster Valley from the Carinthian family of the Sieghardinger[1] and Aribonids.[4] Through the marriage with Richgard, he obtained large possessions in Tyrol and also in Carinthia,[2] for example the Lavant Valley (in modern Austria)[5] and probably also Laško and some other parts in the March of Carniola (in modern Slovenia) like the territories around Ljubljana.[6]

In the year 1044 he documents as ruling Count at Sponheim. In 1045 King Henry III of Germany granted Siegfried the territory of the Hungarian March at the eastern frontier of the March of Austria as a fiefdom. However, he kept and managed this land only for a short period. The Hungarian March was finally dissolved and incorporated under the rule of the Babenberg margrave Ernest of Austria from 1055.

In 1048 Siegfried documents as a Gaugraf in the Tyrolean Puster Valley and in the Carinthian Lavant Valley; he must therefore have already succeeded to his father-in-law Count Engelbert IV as heir to this territory by then. He overtook likewise the possessions of his father-in-law in the Duchy of Bavaria. Besides he soon held the office of a Vogt (reeve) in the bishoprics of Brixen and Salzburg. Siegfried received likewise possessions in Lower Carinthia and in eastern Upper Bavaria. https://en.wikipedia.org/wiki/Siegfried_I,_Count_of_Sponheim

Hedwig-7 and Lavant-1 do not represent the same person because: Different name - not sure where Hedwig-7 fits in, but is same name as daughter-in-law of Lavant and better merged with that profile.

Children: (1) Engelbert I. († 1096), Margrave of Istrien, Count to Spanheim, Count im Pustertal, married Hadwig; (2) Siegfried († 1070) married NN; (3)

Hartwig († 1102), Archbishop of Magdeburg; (4) Hermann († 1118), Burggraf of Magdeburg

AKA: Richgard of Sieghardinger

Hedwig-7 and Lavant-1 appear to represent the same person because: no sources for either profile. I've also proposed merge for the husbands and will propose the merge for son Stephen.
