Thank you for posting the Forde Abbey link. It looks quite delightful, and I can see that it has many of the features which Delaford is said to have.

I had not imagined Delaford to be half as magnificent though. In Ch.14 Mrs Jennings says:

"The estate at Delaford was never reckoned more than two thousand a year,"

I realise there is no direct correlation between the grandeur of a house and the income of an estate, but two thousand a year puts Delaford in the same league as Mr Bennett's estate at Longbourne.
