Princess Herzeleide of Prussia

She was the only daughter of Prince Oskar of Prussia (the second youngest son of Emperor Wilhelm II) and his initially morganatic wife, Countess Ina Marie von Bassewitz.

Countess Herzeleide-Ina-Marie von Ruppin was born in Bristow, Mecklenburg, on 25 December 1918,[1] shortly after the defeat of the German Empire and the collapse of the monarchy.

Herzeleide and her brothers became Princess/Prince of Prussia on 21 June 1920 when their parents' morganatic marriage was recognised as dynastic by the deposed Emperor Wilhelm II.

He was a direct descendant of Ernst Johann von Biron who obtained sovereignty of the Baltic Duchy of Courland and Semigallia in the 18th century.

[4] The couple's honeymoon plans included a visit to Doorn to pay respects to Emperor Wilhelm in exile,[2][4] the bride's paternal grandfather.
