On the 1881 census at 86 Culver St, Salisbury (RG11/ 2072 f 99 p13), the household of Tom Holly included an "Emma Harrison, adopted child, 13, scholar, born Salisbury". I'm trying to figure out who she was and what relationship she bore (if any) the the Holly family.

The mother, Patience Holly, 70, was not far away in Queen Street, working as a monthly nurse in the household of Charles Ling, lay vicar and hosier, a family with with 7 children under 12, one only two weeks old (RG11/ 2072 f36 p12). Of course, Patience's job might have brought her into contact with many orphaned children, and the Hollys seem to have been a big-hearted family, so Emma might not be any sort of relative.

Two of Tom and Patience's sons married women called Harrison, and I wondered whether young Emma might have been a connection of one of them.
George Holly married Annie Harrison in Alderbury 4Q 1875 but she died a year later as Ann Holly aged 30 in Alderbury 4Q 1876.
His brother Thomas Henry Holly married Charlotte Jane Harrison in Alderbury in 2Q 1876 and they had four children. Thomas Henry Holly seems to have died in the Asylum in Devizes in 3Q 1893 and his widow Charlotte remarried a man called Farmer.
I have delved into the background of both of these Harrison women but can't find anything tying them to the adopted child Emma Harrison who was 13 in 1881.

Is this young Emma Harrison's birth registration? 4Q 1867 Tisbury, mmn Lampard?
Where was Emma Harrison in 1871 when she would have been three years old?

This isn't vital to my research, but I do hate these unresolved loose ends!
