Thomas and Ann Stone migrated from Bristol, England to Hobart, Van Diemens Land in 1819. They lived in Hobart for a while (to keep a long story short) and moved to Constitution Hill, near Green Ponds and Bagdad in Tasmania's Midlands. They named their property 'Horfield'.
It's taken me a while to sort out the location and I still don't have a good understanding but it doesn't help that some of these names are obsolete. Green Ponds is now Kempton, Constitution Hill (the area not the hill) is now Dysart, Van Diemens Land is now Tasmania.
