where did the mountbatten name come from

The Mountbatten name is an Anglicised version of the German princely name Battenberg , adopted during World War I to sound less German and more acceptably British.

Quick Scoop: Origin of “Mountbatten”

• The family originally belonged to the German Battenberg line, a morganatic branch of the House of Hesse-Darmstadt in what is now Hesse, Germany.

• The name Battenberg itself refers to a small town in Hesse; literally it means something like “Batten mountain” (Berg = mountain).

• During World War I, anti-German feeling in Britain ran high, so German-sounding titles and surnames at court became politically awkward.

• On 14 July 1917, Prince Louis of Battenberg and his descendants who were living in Britain officially gave up their German titles and translated Battenberg into English as Mountbatten (they even briefly considered “Battenhill” and rejected it).

• Just three days later, the wider British royal family also rebranded itself from Saxe-Coburg and Gotha to the now-familiar House of Windsor , part of the same anti-German re‑naming wave.

In other words, the Mountbatten name came from a World War I–era decision to translate the German princely name Battenberg into a more British-sounding form and formally adopt it as the family surname.

TL;DR: Mountbatten = Battenberg translated into English in 1917 to drop the obviously German look of the name during WWI.
