Who was Queen Victoria's maternal half-sister?

Princess Feodora of Leiningen was Queen Victoria’s maternal half-sister.

Feodora was born in 1807 to Princess Victoria of Saxe-Coburg-Saalfeld and her first husband, Emich Karl, Prince of Leiningen. After Emich Karl died, Princess Victoria married Prince Edward, Duke of Kent, in 1818. Their daughter was the future Queen Victoria, making Feodora her maternal half-sister.

Feodora spent part of her childhood at Kensington Palace with Victoria. The two girls shared a close relationship, although Feodora was eager to leave the restrictive household shaped by the so-called Kensington System. In 1828, she married Ernst I, Prince of Hohenlohe-Langenburg, and moved to Germany.

She remained in regular correspondence with Victoria throughout her life. Feodora is sometimes confused with Victoria’s daughters, but she belonged to the generation before them and was Victoria’s older half-sister, not her aunt or cousin. She died in 1872.
