Hi Frances,
WOW ! Any faster and you would have replied before I had asked the questions ! I am very pleased to hear what you said, as it ties in with my own tentative identification, viz Anthony Preston & margaret Duccan, with William Preston and Alice Taggart as his parents, but all I had was a date of marriage 24 Oct 1721, and Deaths of 6 April 1772 for Wm and 25-12-1771 for Alice (bad luck that !)

Given that the data was very tentative, I did not want to quote it as fact, as it is so easy to do that and then for speculation to become fact. I had not see the will so that is a line to investigate further. Many thanks
