Thank you for going to all that trouble. I have those baptisms too. It's just the later members of the Ernle family at Dilton whom I cannot attach to the tree as yet, because of scanty or defective records. I take it that these folk are descendants of Richard Ernle and Elizabeth Cogswell's sons.
If you check this forum for new postings, you will see that I have reposted here a message about my research which tells you a bit more about what I have discovered so far about the Wiltshire Ernle sib.
You just need to look on the left-hand side of the page and if you click on the heading Family History, you will find a link to wills. There you can search for people to your heart's content. I have copies of all the Ernle wills as well as all the wills pertaining to people from Purton in Wiltshire (plus the variant spelling Pirton). Sometimes you need to be a bit flexible with the use of spellings and wildcards to find what you're looking for.
Other wills, proved in more junior courts (i.e. the diocese of Sarum [Salisbury], and the Wiltshire archdeaconries of Wilts. or Sarum, as well as the Dean's Court, and the peculiar courts [yes, that's the term used]) can be checked by sending a message of enquiry to the Wiltshire and Swindon Record Office via their website. Once contact is made, you can order any will, administration, bond or inventory from them and pay once you receive their invoice. Alas, they don't have a credit card facility, or I would have ordered a lot of things more easily.
