I was using the Geni relationship pathway as a guideline for adding this profile to my personal tree on Ancestry. I ran into conflicting Wikipedia pages. The one used as a source for the Geni profile doesn't have any sources I'm able to check; whereas this one does but the problem is, it has a totally different maternal line.
Both Wikpedia sources agree that Bernard III is Henry's father, but whereas the one used for the Geni profile has Henry's mother as Brigitte The Wikipedia page below has Bernard III only married once, to a woman named Judith, no mention of a Brigitte. However, this page does offer sources that I was able to check:
https://pl.wikipedia.org/wiki/Bernard_III_Aska%C5%84czyk
I checked one of the references and it does indicate Henry's mother was Judith, not Brigitte. Again, not even a mention of Bernard having any other wife than Judith:
Bernhard III, Count of Aschersleben, Duke of Saxony
----------- ------
around 1140- probably Feb. 1212
Buried: in the Benedictine monastery in Ballenstedt
oo Judith, daughter of Mieszkos III. from Poland
* around 1154, + before 1202
The youngest son Albrecht the Bear received the county of Aschersleben in 1170 when the askanian heritage was shared . After the fall of Henry the Lion in 1180, he was vested with the eastern half of the Duchy of Saxony , but encountered the resistance of the spiritual and secular princes and counts striving for greater autonomy. While Bernhard renounced any influence in Westphalia and Engern, he claimed sovereignty over the counties of Holstein , Ratzeburg , Schwerin , Lüchow and Dannebergwithout being able to assert itself completely. The growing influence of the WELFEN and the inconsistent attitude of the emperor caused him additional difficulties . In 1197 he was made a candidate for throne under the leadership of Archbishop Adolf of Cologne , but refused and remained loyal to PHILIPP VON SCHWABEN . Only after his death did he join the OTTO IV party . - The focus of his possessions was in the askanian countries. After his death, the eldest son Heinrich received the Askan possessions between the Harz and Middle Elbe ( Anhalt line ), the younger Albrecht Ibecame Duke of Saxony ( Wittenberger Lineage ).

Based on sourced vs. non-sourced documentation, I believe the Geni connection is incorrect and the mother of Henry I should be Bernard III's wife Judith.
