Maybe the problem is that she's not a Cornell, but a Cornwall of Standlake. See Visitations of Oxford, p. 158.
When in doubt, follow the land records.
"An estate centred on Standlake Manor, a house on the south side of High Street so called from c. 1860, (fn. 5) was built up from the later Middle Ages by the Cornewell or Cornwall family and by their successors the Yates, following the marriage before 1487 of Margaret, daughter and heir of John Cornwall (fl. 1480), to Edmund Yate (d. c. 1516) of Charney Bassett in Longworth (then Berks.). Edmund Yate's estate, not all of it derived from the Cornwalls, descended to John (d. 1545), Robert (d. 1554), James (d. 1608), and Francis Yate (fl. 1613); (fn. 6) he or another Francis sold it in 1647 to Richard Hyde (d. 1665), gentleman..."
"The house's timber-framed main range, aligned along the street, is of the 15th century, and was built perhaps by John Cornwall. "

Looks like somebody got grandfather Edmond mixed up with grandson Edmund, skewing dates all over the place.
This is probably Edmund m. Margaret Cornwall, with his birth date hashed and robbed of all his children: Edmond Yate
According to both Oxford and Berkshire, William (Gate) Yate, of Charney was the first identified member of this family, and his wife was *unknown* (i.e. she wasn't Margaret Cornwall!).
"Sources" for "John Attayate" as his "father" are paywalled.

The Yate home was at Charney Manor from 1332. Some of those to live there were William, his son Edmund, and grandson Richard. Adjacent to it is St. Peter's Church, Charney Bassett, Berkshire, ENG, built in the 12th century to replace an earlier Saxon structure.
Hunt, J.G. English Ancestry of George Yate of Maryland.
Vistation of Berkshire, 1566.
Ran a check against the Visitations of Berkshire (Buckland and Lyford branches) and Oxford (Standlake, Witney and Bendlett branches). Insofar as they are correct (never a certainty), they're now OK down to about 1620 or so (added the Buckland Baronets from Cracroft).
Exactly *how* George Yate was "cousin" to Jerome White is still not entirely clear. He was so referred to *before* he married Mary Wells, so it's not *that* connection. There seem to be a couple of marriages that would make him a relatively distant cousin.
Yateshistory.net doesn't quite match Visitations, dates are WAGs, etc. Primary interest of the compiler seems to have been a Spencer-Churchill connection (i.e. Princess Diana). Also they believe in Tudor-Jacobean era middle names, har de har har.
