I would be delighted to have a copy of the will, many thanks. I presume you have it in electronic form, and if so perhaps you could kindly send it to my e-mail address, which is Spandrel717@Hotmail.com.
I was thinking a bit more about the £500 legacy to Anne Sackville (Turner) which appeared in Lord Dorset's earlier will dated 1684. Anne was aged about 17 at the time, and she married Edward Turner four years later. Turner family tradition says that on her marriage she received a marriage portion of £1,000 from her father, and I should think that took the place of the sum she had been going to receive as a legacy.
The annuity given in her father's final will might have seemed, if you like, a bonus, because in the normal way an illegitimate child would probably have had little expectation of receiving anything (and certainly no right to do so) on the death of his/her father. Anne of course died before her husband Edward Turner, and I believe that Lord Dorset's son, the Duke of Dorset, gave instructions on Anne's death that the annuity was to continue to be paid to Edward.
I don't think anyone could accuse the Sackvilles of not behaving generously to Anne and her family.
