The infant princess has been named Wilhelmina Pauline Helene. She weighed at birth 7lbs 5 ozs and is 20.5 inches tall.
The name Wilhelmina is not uncommon in the Bentheim und Steinfurt princely family.
Ludwig, the first Prince of Bentheim und Steinfurt (1817) married Princess Juliane Wilhelmime of Holstein-Glücksburg. Their son, Alexis, Prince of Bentheim und Steinfurt, married Princess Wilhelmine of Solms-Braunfel.
Hereditary Prince of Bentheim und Steinfurt, Carl Ferdinand, 40, married Elna-Margret Rinn on July 21, 2007. Their son, Prince Jonathan Alexei Victor was born at Münster on December 24, 2008.
Princess Elna-Margret told a reporter earlier this year, after her second pregnancy was announced, that conceiving a second child had been difficult. She celebrated her 39th birthday on June 14.
"We did not want to have such a big age difference between our children." she told the German magazine, Gala. "It felt like all of our friends were having baby after baby, but it did not work out for us. We are really looking forward to our child."
The original interview with Gala was on January 16, 2018. At the time, Princess Elna-Margret said she hoped that their second child would be a girl.
Carl-Ferdinand is the eldest of four children of Prince Reinhard and Angelica Emmerman. He is the adopted heir of his uncle, Christian, the Prince of Bentheim und Steinfurt, who will celebrate his 95th birthday in December. Prince Christian and his late wife, Countess Sylvia von Pücker, were unable to have children of their own.
