I always pictured her with 14 years old (that baby face *_*) but she shouldn't be very old, since she's the youngest and lowest of the house, and if she has all that big family and dumped the school at eleven, she must not be unemployed a long time, to support her family (on season 1) and she's still a bit childish at the end. But who knows, this show has a weird chronology.

I think she could be around 14/15 in the beginning of the series. In reality a scullery maid would be even lower than Daisy, who holds a "higher position" of kitchen maid. Girls could enter service as young as 11 to begin work as a scullery maid.
