This is the transcribed will of William Buckner of Cumnor Parish, Berkshire, England, 1558 (Archdeacon Berks. wills reg. D.188, LDS film #1,041,804)
The great mystery with this will is who's not in it. Several independent records indicate that Thomas Smyth, a mayor of Oxford, married Rose Buckner in 1553, daughter of William Buckner of Botley (in Cumnor parish) and Dorothy Huckvale. At first glance, the William Buckner with his wife Dorothy in this will is a pretty good candidate to be William Buckner of Botley, who is known from other records as well. Rose had died by 1585 when the widow Dorothy Buckner wrote her will, so she would naturally be missing in it, but it is odd that neither she nor her prominent husband are mentioned in the present will, though John Smyth and his wife are on the Christmas list at the end. A son William Buckner is also omitted from the present will though (he is known from his mother's will 18 years later), so it is possible that several children were omitted for some reason (his apparent cousin, or possibly brother, Thomas Buckner of Whitley did the same thing in his 1587 will). Pleasants (the farm he lived at) was also in Botley, so place and the names are consistent with the idea that this is William of Botley. I'm still a little hesitant because of Rose's absence, but for now I'm working under the assumption that this is the same William Buckner of Botley.
William Bucknour is mentioned as a tenant of Botley lands called Nutbeames, Glo[vers], Herefords, and Colys in 1540 when they were granted by King Henry VIII to Sir John Williams.(Letters and Papers, Foreign and Domestic, of the Reign of Henry VIII: Preserved in the Public Record Office, the British Museum, and Elsewhere in England, Volume 15, p. 169). He held the same lands in a 1538 rental survey. A William Buckner appears in Botley in a 1524 lay subsidy list as well, though I'm not sure if that's the present William Buckner or perhaps his father. One should also note that "William Buknour" was listed as a free haberdasher of London in 1538, but it appears that this is a mistake for "William Bicknor" who was a master haberdasher in London at the time.
One open question is the relationship of William Buckner of Botley to Richard Buckner of Cumnor (d. 1548). Richard named a son William in his will who may have been the same as this testator, but as William of Botley had to have been born prior to 1520 (to have a one daughter married in 1553), I think it is unlikely that this William could have been Richard Buckner's son (though still not ready to rule it out). The families of William (d 1558) and Richard (d 1548) interacted closely well into the 1600s, so they were almost certainly either son and father or brothers.
The birth order of the children is a little obscure, though John's occurrence first and his general standing in the community later in life leads me to assume that he was the eldest. The omitted son William is something of a puzzle. There is some reason to think that he is William Buckner of Chawley who died testate in 1618. Dorothy Buckner's will mentions that William's eldest son was named John, which would be consistent with William of Chawley, whose eldest son John of Chawley predeceased him in 1599. Richard had a large number of children in Cumnor parish, though no will of his has come to light and I haven't been able to trace any of his family line beyond their christenings. His mother mentions a number of them in her will, which allows us to connect them to the christening records with confidence. Richard inherited the farm in Botley, so it is rather puzzling that his large family disappeared so completely, but there seem to be no Buckners in Botley by the time of the 1611 lay subsidy. (The Chawley property seems to have remained in the family up into the 1700s though.) Thomas is the most obscure of the sons, and he had probably died by the time his mother's will was written in 1585.
There are several ambiguous personal and place names. The most significant is probably the location of the house that Thomas Buckner inherited. Others have read this as "parish of Eaton" , which is contextually satisfying, but the form of the initial letter is very difficult to reconcile with a captial 'E'. It most resembles a 'P' to me, but there isn't a "Paton" parish that I can find (Potton, Bedf., Porton, Wilts.?). The conspicuous overbar above the 'a' probably indicates abbreviation, most likely 'n' or 'm', which might suggest Panton or Ponton, both in Lincolnshire. Since this will was probated in the archdeaconry of Berks, it has to have been a parish within the archdeaconry however. Otherwise, the will would have to have been probated in a higher court. In a stretch, I could read "Fa[ring]ton", for Faringdon, Berks. - the overbar does suggest a longer abbreviation than a simple 'n' or 'm'.
The biggest corrections I would make to previous readings of this will are the names of the daughters "Mare" (otherwise read as "Maye") and "Daye" , which appear to me to be a variant of Mary and the surname Day respectively. Ronald Day was a neighbor, and it seems logical that he was a son in law of William Buckner. The list of names that are given a bushel of barley near the end are probably mostly surnames, presumably neighbors.
A couple random things to note are the archaic plural "childer" for children and the obscure legacy "to Pyp to Mother Glover Young Glover by bond". The date on the 2nd line is very obscure, but I believe I can parse it. The first letter is just "a". The next character resembles a 'y' but is actually the thorn (þ) used to represent "th", with a flourish, so it's an abbreviation of "a thousand." The next is vC, a way of writing 500 in Roman numerals (5 × 100), and then "l[..]" which is a straightforward Roman numeral for 50-something, with the last part lost in the edge of the page. It's probably lvij (57) or lviij (58), more likely the former from the length of it.
I've tried to preserve the line arrangement so anyone who wants can compare this to the original image. I don't claim perfection, and there are some things that can be interpreted different ways. The notation {ER} and such indicates a superscript abbreviation. These are common in period documents, though sometimes they can be a little idiosyncratic.
