Venn: Adm. sizar CHRIST'S 14 Apr. 1668; son of John (probably CCEd ID 159699); born Uppingham; matric. 1668; BA 1671 1671/2; MA 1675; ordained deacon (Peterborough) 19 Sep. 1675l priest 29 May 1681;
Additional material in Venn: C of Langham, Rutland 1683-99; C of Egleton 1692-9; ?Usher Oakham School 1660.
DK Shearing (PhD thesis Inst. Ed. London "Education in the Peterborough Diocese in the Century following the 'Glorious Revolution' 1688" lists him as usher of Oakham G.S. from about 1671 to at least 1711. His curacies at Langham and Egleton, which were chapleries of Oakham parish, fit with this.
Suggestion that John (CCEd ID 159699) derives from dates, geography and that Sampson appears to have been a family given name.
