I've been at this two years so I thought I had a good grasp on the candidates......not so fast. Enter Thomas Sackville, Lord Buckhurst, Earl of Dorset.
I was very dismissive at first because I had already pinned Oxford as the principle author. But two books by Sabrina Feldman have blown the doors off that theory.
There's not much to be found on him on the internet. This is about as much as you'll find https://www.geni.com/people/Thomas-Sackville-KG-PC-1st-Earl-of-Dorset/6000000000151481960

One of the more fascinating aspects:
Dr. James Anderson, New Book of Constitutions of the Fraternity of Freemasons, 1738, p. 81
Among his other youthful interests was a zeal for freemasonry, and he became in 1561 a grand master of the order, whose headquarters were then at York. He resigned the office in 1567, but while grand master he is stated to have done the fraternity good service by initiating into its innocent secrets some royal officers who were sent to break up the grand lodge at York. Their report to the queen convinced her that the society was harmless, and it was not molested again/quote]
