Duke Henry of Mecklenburg-Schwerin

Biography.
Heinrich Wladimir Albrecht Ernst of Mecklenburg-Schwerin was born on 19 April 1876 in Schwerin. He was the youngest son of Frederick Francis II, Grand Duke of Mecklenburg-Schwerin, and his third wife, Princess Marie of Schwarzburg-Rudolstadt.
He was inaugurated as Prince of the Netherlands on 6 February 1901, and married Queen Wilhelmina on 7 February 1901, in The Hague. Their only child together, Juliana, was born in 1909. She succeeded Wilhelmina as queen on the 4th of September 1948 at the latter's abdication. Heinrich, however, also produced at least one illegitimate child: Pim Lier. Born in 1918, Lier rose to prominence in post-war Dutch politics as chairman of the right-wing extremist Centre Party. The birth of a son out of wedlock was likely to be only symptomatic for the duke's increasingly strained relationship with his wife. This became all the more clear at the time of the opening ceremony of the Amsterdam Summer Olympics in 1928. Even though Heinrich was not only to attend, but even to preside over the festivities, Wilhelmina did not even bother to show up, stating that her personal religious conviction that this type of event should not take place on a Sunday kept her from doing so.
He was the 279th Grand Cross of the Order of the Tower and Sword in Portugal and the 1,157th Knight of the Order of the Golden Fleece in Spain in 1924.
He died, at the age of 58, on 3 July 1934 in The Hague, Netherlands.
Scouting.
He successfully merged the two Dutch Boy Scout organisations Nederlandse Padvinders Organisatie (NPO, Netherlands Pathfinder Organisation) and the Nederlandse Padvinders Bond (NPB, Netherlands Pathfinder Federation) on 11 December 1915 to form De Nederlandse Padvinders (NPV, The Netherlands Pathfinders). He became the Royal Commissioner of that organisation and he asked Jean Jacques Rambonnet to become chairman in 1920.
Extramarital relationships.
Prince Henry was known to have had numerous extra-marital affairs. It is rumored that, overall, Prince Henry fathered between three and ten illegitimate children, but firm proof remains elusive, except for Albrecht Willem Lier, known as the above-noted Pim Lier (22 Jul 1918 – 9 Apr 2015). During her widowhood, Queen Wilhelmina paid monthly allowances to three known ex-mistresses: Julia Cervey in Geneva (two hundred guilders per month); Wilhelmine Steiner in Zurich (five hundred guilders per month); and Mien Lier-Wenneker (1887-1973), in The Hague (five hundred guilders per month). Mien Abbo-Wenneker (later Lier-Wenneker, 1887-1973), gave birth to a total of six children; the older two, sisters Christina Margaretha Abbo & Edith Abbo (later Sheep-Abbo) were ostensibly the daughters of Mien’s first husband, Dhr. Abbo, but strongly rumored to have been fathered by Prince Henry. In 1919, Mien married Lieutenant Jan Derk Lier, a former aide-de-camp to Prince Henry. A grant of one hundred thousand guilders was arranged for Lt. Lier from the State by police chief François van 't Sant, whom Queen Wilhelmina engaged to verify the facts of her husband’s extramarital relationships and children. This, plus a monthly allowance to the Lt from the state of one thousand guilders, was in return for his commitment to "the three children of HRH.”
The male parent of the remaining three children was not verified as being either Prince Henry or Lt. Lier. Subsequent to their birth, no additional allowance was settled on the family; in fact, the monthly allowance of one thousand guilders to Lt. Jan Derk Lier was halved by van't Sant after a short period, although the allowance to his wife continued.
