Fourteen years ago I purchased a darling female King Charles Spaniel from Chacombe Priory near Banbury. Is it still in existance?

There are most probably more informed people than me who will answer your query fully , but as a matter of interest I did a search on Google.com for Chacombe Priory + Dogs and came up with this site :

There is an address of one of the trustees whose name you may recognise . failing that , the site http://www.cavalierclub.co.uk may help if you email them
