Ok now this is what we have
The Thomas Perry, Priest died in South Africa 1762, do we think this is the same Thomas Perry buried at St Michael's?
Or have we this:
Thomas Perry died 1762 m Ann
Issue:
George died 1761
Thomas born abt 1734 & died in South Africa 1762
Ann listed in will alive in 1762 and single
Then perhaps
John Perry, was a brother to the Thomas Perry that married Ann or is he another son of Thomas & Ann?
This means like I thought that Thomas Perry that married Ann would be born around 1700 and I assume this is the son of another Thomas Perry, the one from Gloucestshire said to be born there and gone to Cambridge Uni abt 1692 (although he is not listed at Cambridge, one assumes the uni list not complete)

The eldest son and heir (of Sir Thomas Leigh and Alice Barber), Rowland Leigh, esq. of ... and, thirdly, Joan, daughter of Thomas Perry, esq. of the city of Gloucester, and had Thomas Perry born 23rd December, 1674 of the University of Cambridge, says he died in 1688, that does not make sense as he would have to be at least 18, to have been in the Cambridge uni. I think this Thomas Perry, 1674 has a son Thomas Perry of Cambridge, who in turn has Thomas Perry that married Ann & John Perry the cap maker 1750
Theories & further info appreciated

PS
Could this be our Thomas?

Puts him Born in Newmarkert Cambridge 1701, but who was his father?
The 1727 baptism of Ann fits nicely for the above couple
