Pace Foster and Venn, I do not think that the same person is both R of Nuffield and V of Bradwell -- the different dates of death would tend to support this.
Venn: Thackham, Thomas, M.A. 1652 (Incorporation in another University. It conferred the privileges of their degree.'Incorp. from Oxford). S. of Thomas, of Reading, Berks., gent. Matric. (Magdalen Hall, Oxford) Oct. 23, 1635, age 16; B.A. (Oxford) 1639; M.A. 1642. Fellow of Magdalen, 1648, by the Parliamentary Visitors. V. of Sydling St Nicholas, Dorset, 1663-5. R. of Nuffield, Oxon., 1668. V. of Bradwell, 1668. Will (C. C. Oxford) 1691. (Al. Oxon.)
The problem with this identification and linkage is that the date of subscription on ordination is later than the subscription on appointment as R of Nuffield. But the R of Nuffield and the ordinand are both stated as having the degree of MA.
