Thanks. I think the photo could be either Julia or Beatrice. It's hard to say because 3 year old babies still have baby fat which makes them look a bit different from older ones. The hairline is very close to Beatrice's though and I personally think the girl looks older than a 10 year old, so I would guess this is Beatrice aged 14.
And she has long and straight thumbs (like mine

) on both photos (the last one you posted and the one of your profile)
