She is on the 1911 census - but transcribed by FindMyPast as Henrietta (the same name as her sister!).
I can't give details regarding 1911, but I can confirm her father's name is Philip.
1901 census has her family here:
Reference RG13, Piece 2836, Folio 128, Page 5
1, 11 Court House, Cheapside, Birmingham
Andrews, Philip G Head M 42 Nail Caster b Aldershot, Hampshire
Andrews, Emily M Wife F 30 Laundress b Dover, Kent
Andrews, Henry P Son M 10 b Birmingham
Andrews, Henrietta M Daughter F 8 b Birmingham
In 1891 the family is here:
Reference RG12, 2384, 50, 34
3, 11 Court, Milk Street, Birmingham
Andrews, Philip Head M 31 Boatman b Birmingham
Andrews, Emma M Wife F 21 b Birmingham (simply says "Do"- ditto)
Andrews, <unnamed> Son M 2 months b Birmingham
But I can't find the marriage?
