1662 signatory as D.D. rector of Corsley on letters testimonial of Robert Abbott (ID 7387).
No identification in Venn/Foster, but other Yarners come from Ireland.
Boyton, Wilts. PRs (WSRO 1507/2): 1646 "Johannes Yarner pastor Boytonensis, pro tempore. nuperrim' minister Andoveriensis." and 1650 "John Yarner, curate ejected". The name is so rare that there is a strong possibility of this being the same man as the R. of Corsley.
