One of the strangest aristocractic female names ever:
Lady Feodorowna Cecilia Wellesley (1838 - 1920).
In Russian ears, a girl called Feodorovna as a first name sounds like a girl named Johnson in Anglophone ears, doesn't it?
She was the daughter of the British diplomat Henry Wellesley, 1st Earl Cowley, who was British ambassador to France 1852–1867, i.e. during a most anti-Russian period (the Crimean War). But I don't know where he was posted when she was born i 1838. In Russia, with Empress Alexandra Feodorovna as godmother?
The empress condescending to be godmother to a grandniece of the Duke of Wellington is perhaps not so unlikely. Lady Feodorowna married Francis Bertie, 1st Viscount Bertie of Thame, another wartime British ambassador to allied France (1905 - 1918). They had one son with a similar odd name: Vere (ancient aristocratic surname) Bertie, which sounds like it should have been reversed: Bertie Vere!
Even though Feodora was the name of a few 19th-century German princesses, the names Feodora (Theodora) and Feodosia (Theodosia) don't seem to be in use in Russian anymore, but are archaïc or monastic.
