Whakaotihia te rerenga e whai ake nei: I whakaakona a Louis, ko te ingoa noa iho o Louis, me tana tuakana a Frederick VI. I ako tahi rāua i Geneva, ā, i te tau 1788, ka uru tahi rāua ki te ope o Prussia. I te tau 1793, i whawhai ia i te
Te Pakanga o Pirmasens. I te tau 1798, i whakatairangahia ia hei rangatira. I te tau 1804, i whakatairangahia ia ki te koromatua o te koromatua, a, i marenatia ia ki a Princess Augusta Amalia o Nassau-Usingen, tamahine a Frederick Augustus, Duke o Nassau. Ko tenei "marena rangatira" me te tamahine a te rangatira tata he mea pouri, na te mea i aroha ia ki a Count Frederick William o Bismarck. I mutu te marenatanga ki te whakarere. I marenatia a Augusta Amalia ki a Frederick William; kaore a Louis William i marena ano. He maha atu nga korero a Ricarda Huch i roto i tana "Count Mark me nga Rangatira o Nassau-Usingen. He haurongo pouri" o 1925.
