Prince Sigismund of Prussia (1896–1978)
Prince William Victor Charles Augustus Henry Sigismund of Prussia (; 27 November 1896 at Kiel – 14 November 1978 at Esparza, Costa Rica), was the second son of Prince Henry of Prussia and Princess Irene of Hesse and by Rhine. He was the nephew of Kaiser Wilhelm II and Tsarina Alexandra of Russia. As the great-grandson of Queen Victoria through both his parents, he was the only one of three brothers who did not have the hemophilia common among her descendants. Life

Marriage and issue
On 11 July 1919 at Hemmelmark, he married Princess Charlotte of Saxe-Altenburg (4 March 1899 – 16 February 1989), the eldest daughter of Ernst II, Duke of Saxe-Altenburg. They had two children:

 Barbara Irene Adelheid Viktoria Elisabeth Bathildis (2 August 1920 – 31 May 1994), married Duke Christian Louis of Mecklenburg
 Alfred Friedrich Ernst Heinrich Conrad (17 August 1924 – 3 June 2013)

Costa Rica
Prior to emigrating from Europe to Central America, he served as a marine officer. In 1927, Sigismund and his family resettled in Costa Rica  three years after his son Alfred (1924–2013) had been born in Guatemala. He planned to engage in banana and coffee planting on land he owned there. In 1957, Sigismund returned to Germany to meet with Anna Anderson whom he recognized as his cousin Grand Duchess Anastasia. During this visit he also met and acknowledged Marga Boodts who claimed to be Grand Duchess Olga Nikolaevna of Russia and Ceclava Czapska who claimed to be Grand Duchess Maria Nikolaevna. In 1972, he once again reaffirmed his belief when talking to BBC journalists Anthony Summers and Tom Mangold, who were writing the File on the Tsar. Sigismund died in Puntarenas on 14 November 1978.
