Baby Name Poll Results

Hey, I’m writing a book and I need some advice on my characters names. For the older brother I was thinking Vincent but he always goes by Vinnie and I was considering the fathers name to be Vincent, known as Vincent? The family are sporting celebrities, mainly the dad but the two children are very high up in their sports too. The daughter, who is the main character I’m thinking of calling Georgina but know as Georgie. I still need a name for the mother. They are an English family, living in London but moving in between America and the UK. And their surname, I was thinking Stellas or Stilas Silas (is it pronounced See-las or Sigh-las?) Suggestions welcome for all names. Thanks!
