"At some time between 1530-1540 William Bullock of Stratfield Mortimer [Berkshire] married his third wife, Elizabeth Bellet, thought to have been the daughter of John Bellot of Moreton, Cheshire."
This tree is taken from a book written by Rev. Llewellyn C. W. Bullock in 1905, who seems to have used (as at least one of his sources) a pedigree collected by William Berry and published in 1838. This pedigree can be found on pages 645-648 of Publications of the Harleian Society volume 14(1879). It links the Bullock family of Great Wigborough, Essex to the Bullock family of Arborfield, Berkshire. However, the dates of the Essex pedigree don't match the dates of the Berkshire pedigree, unless one is willing to believe that both the 1532 and the 1566 Visitations of Berkshire ignored the previous several decades of marriages and births.
If a William Bullock married an Elizabeth Bellet between 1530 and 1540, as stated here, he wasn't the son of Thomas Bullock and Alice Kingsmill (and there is no reason to assume that Elizabeth Bellett was his third wife).
