Given the following context:

The story is partially inspired by the Davies brothers' older sister Rose, who emigrated to Australia in 1964 with her husband Arthur Anning. Her departure devastated Ray Davies, and it inspired him to write the song "Rosy Won't You Please Come Home", included on the 1966 album Face to Face. The lead character in the album, the fictional Arthur Morgan—modelled after Anning—is a carpet layer whose family's plight in the opportunity-poor setting of post-war England is depicted. Writer Julian Mitchell detailed the story line and characters in depth, explaining in the liner notes for the album's LP release:
Arthur Morgan ... lives in a London suburb in a house called Shangri-La, with a garden and a car and a wife called Rose and a son called Derek who's married to Liz, and they have these two very nice kids, Terry and Marilyn. Derek and Liz and Terry and Marilyn are emigrating to Australia. Arthur did have another son, called Eddie. He was named after Arthur's brother, who was killed in the battle of the Somme. Arthur's Eddie was killed, too—in Korea.
Davies would later comment in his autobiography, X-Ray, that Anning later "told me that he ... knew it [Arthur] had been partly inspired by him ... [it] reminded him of home ... I told Arthur that I felt guilty for using him as a subject for a song, but he shrugged off my apology, saying that he was flattered." With an underlying theme of nostalgia, the songs describe the England that Arthur once knew ("Victoria", "Young and Innocent Days"), the promise of life in Australia for one of his sons ("Australia"), the emptiness of his superficially comfortable life in his home ("Shangri-La"), the resolve of the British people during the Second World War ("Mr. Churchill Says"), the privations that marked the austerity period after the war ("She's Bought a Hat Like Princess Marina"), and the death of his brother in World War I ("Yes Sir, No Sir", "Some Mother's Son").

answer the following question:

What is the first name of the person whose departure inspired the song, "Rosy Won't You Please Come Back?
