Lothair Udo was betrothed to Eilika of Saxony, daughter of Magnus, Duke of Saxony, and Sophia of Hungary. However, his attention was diverted to the House of Helperich, towards Count Helperich's enticing sister Ermengardam. He married this woman, the count's sister Irmgard, daughter of Dietrich, Count of Plötzkau, and Mathilde von Walbeck, daughter of Conrad, Count of Walbeck. Eilika moved on and married Otto the Rich, Count of Ballenstedt, and was mother to Albert the Bear, the last Margrave of the Nordmark and first Margrave of Brandenburg. This provides an interesting twist in the history of the county of Stade.

Lothair Udo and Irmgard had four children:

Lothair Udo was succeeded by his brother Rudolf as margrave and count upon his death.
