Parker and his fiancée, Soleil Charvat (whose mother is a Greenwood), had moved into the Huntingdon mansion. Giles Huntingdon died soon after his wife and had left the house to his grandson. Parker’s aunt, Beatrice, had gone to university (she’s younger than he is) but Cornelius still lived in the house. The house was big enough (three storeys) and he didn’t have a lot to do with his nephew anyway.
Soleil organised the wedding party and invited parents on both sides (Beau and Veronica and Theophile and Valley) as well as one of her brother’s, Montagne, and Parker’s uncle, Chip.
