Hi David,
Thank you for that info

I just noticed Paul is from New Zealand in his profile. Whilst googling for Thornhill info I found this which may or may not be related;
"google"
Janus, Letters from the Thornhill Family in New Zealand.
There are also papers from the Thornhill Collection held in the Hunts Archives. The last Thornhill ( Noel) died without issue in 1956 and the papers donated.
The Thornhills originated in Fixby, Yorkshire and arrived in Diddington abt 1730.
They held estates and houses in ;
Boxwith, Cambridgeshire
Dowdyke Hall, Lincolnshire
Oxfordshire, Huntingdon, Offord Darcy, Southoe, Duloe
London, Bread St, Holloway, Angel Islington
A fitting posting for my 3000th as I have no Gentry in my line

Cheers,
Trish
