I did a search for a Christiana born in 1850 at St.Austell. on the censuses:
Christiana Higman 1852 St Austell- an inmate in a blind institution (1911, 1891, 1871) but living with parents in 1861, so we can rule her out.
Christiana Ede b 1853 (1891, 1901 and 1911) wife of Alfred Ede. mother living with her Elizabeth, ruled out
The only Christiana left (discluding 2 children on the 1861)
is a Christiana Matthews b 1848 St Austell working as a servant in Camberwell. Although it says she's unmarried, the thing is she went to London- to be with her mother, or near her, perhaps? It's a small lead, but it could be worth a shot? This is, just however searching for Christiana, and who knows what she might have been transcribed as. I cannot find anything on her under Harry.
