Cannot certainly be identified with John Ashcroft presdented to Hagworthingham in 1708, especially given Venn (which may be in error, of course) ewhich gives two other Ashcrofts at Hagworthingham in first half of eighteenth century.
i.e.
John (nd at Hagworthingham) but only mat in 1708 and not MA according to Venn:

and THOMAS (MA and ceases as Fellow of Clare in 1708):
