Question: When is Henry Ii, Margrave Of The Nordmark's father's birthday?

Knowledge 1: Henry II, Margrave of the Nordmark
Henry II (1102 – 4 December 1128), Margrave of the Nordmark, also Count of Stade (as Henry IV), son of Lothair Udo III, Margrave of the Nordmark, and Irmgard, daughter of Dietrich, Count of Plötzkau, and Mathilde von Walbeck.Henry assumed the title of Margrave of the Nordmark in 1114 from Helperich of Plötzkau, who was appointed margrave until Henry came of age.The previous margrave in this dynasty was Henry’s uncle Rudolf I, who was also his guardian.Rudolf was deposed by Emperor Henry V because of conspiracy against the crown, and was replaced by Helperich as an interim measure.Henry assumed the titles of Count of Stade and Margrave of the Nordmark in 1114.Henry was married to Adelaide of Ballenstedt, a daughter of Otto, Count of Ballenstedt, and Eilika of Saxony.Adelaide was therefore the sister of Albert the Bear.There are no known children as a result of this union.Henry was succeeded as margrave by the son of Helperich, Conrad of Plötzkau. [SEP] Knowledge 2: Lothair Udo III, Margrave of the Nordmark
Lothair Udo III (1070-1106), Margrave of the Nordmark and Count of Stade (as Lothair Udo IV), son of Lothair Udo II, Margrave of the Nordmark, and Oda of Werl, daughter of Herman III, Count of Werl, and Richenza of Swabia.Brother of his predecessor Henry I the Long.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.
Knowledge 1: Henry I the Long, Margrave of the Nordmark
Henry I the Long( c. 1065 – 27 June 1087), Margrave of the Nordmark, also Count of Stade( as Henry III), son of Lothair Udo II, Margrave of the Nordmark, and Oda of Werl, daughter of Herman III, Count of Werl, and Richenza of Swabia.Henry married Eupraxia of Kiev, daughter of Vsevolod I, Grand Prince of Kiev, and his second wife Anna.There were no children as a result of this marriage, and Eupraxia, widowed, married next Henry IV, then King of Saxony, who became Holy Roman Emperor.Raffensperger suggests that Henry's motivation in marrying Eupraxia was to bring Saxony closer to Kiev.In fact, the marriage may have been arranged by Oda of Stade, daughter of Lothair Udo I, Margrave of the Nordmark, who had married Sviatoslav II, Grand Prince of Kiev.Oda is identified as a relative of Henry ’s father Lothair Udo II as well as a niece of Henry III, Holy Roman Emperor, and Pope Leo IX.Upon his death, Henry was succeeded as margrave and count by his brother Lothair Udo III. [SEP] Knowledge 2: Rudolf II, Margrave of the Nordmark
Rudolf II( died 14 March 1144), Margrave of the Nordmark, and Count of Stade, Dithmarschen and Freckleben, son of Rudolf I, Margrave of the Nordmark, and Richardis, daughter of Hermann von Sponheim, Burgrave of Magdeburg.Rudolf, the traditional heir to the margraviate assumed the title upon the death of his predecessor Conrad von Plötzkau.A chronicle of the 15th century reported that Rudolf resided in Burg, Dithmarschen( Bökelnburg).He ruled with a heavy hand and demanded his grain tithe even after several years of drought.The Dithmarscher farmers used a ruse to get rid of their unpopular regent.Hidden in sacks of corn were weapons.As agreed, they opened the bags at the sound of the battle cry" Röhret de Hann, snidet de sac spell!"( Shall ye touch hands, cuts the bag volumes).They set the castle on fire, killed the count along with his wife, and so won their freedom.This event is still recounted today in performances at the castle.Rudolf was married to Elisabeth, daughter of Leopold I the Strong, Margrave of Styria.No children are recorded of this union.With the death of Rudolf, the male line of the Margraves of the Nordmark died out.After the death of Rudolf, his brother Hartwig transferred his inheritance to the Archbishopric of Bremen in return for a regrant of a life interest, presumably to obtain a powerful protector against the aggression of Henry the Lion.The move was ineffective, as Henry took possession of the lands and captured both Hartwig and the archbishop Adelbero, releasing them only after they agreed to recognize his claim.Rudolf ’s successor as Margrave of the Nordmark was Albert the Bear.Upon Rudolf's death, his brother Hartwig succeeded him as Count of Stade.
