Beautiful family photos ;-)
Ortrud is a strange name, I've never heard ut before.... was she German?
Her father was Albrecht of Schleswig-Holstein and she was the only child by his 2nd wife, Hertha Pss zu Isenburg-Büdingen. Ironically, Albrecht's first wife was named Ortrud. Two of Ortrud's brothers were KIA in WW2. Her 3rd brother, Friedrich, married Alexandra of Mecklenburg-Schwerin who was the first cousin of Ortrud's future husband. Despite the age discrepancies, Ortrud was first cousin to Duchess Victoria Adelheid of Saxe-Coburg-Gotha, Princess August Wilhelm of Prussia (VL's sister-in-law), Princess Helena of Denmark (married to Prince Harold, another cousin of Ernst August Sr), amongst others. She thus had a lot of connections to both her future mother-in-law and father-in-law.
