I did try the advanced search but not children's home.
There were the two workhouses in Exeter I discovered Refhills St Thomas and the other which I assume was in the Heavitree area.
Also tried a search for Phoebe my grandmother under surname of Foster and Woodhouse.
The Woodhouse family has been a thorn in my side. A nefarious family ...all of them. As I write this it brings to mind Phoebe at a young age (teens) was sent away to a facility for stealing a lace collar from her employer. Now I'm wondering if she could be in a prison
