No John Rs bapt Andreas 1815 as far as I can see. He wasn't John RADCLIFFE bapt.10 March 1816 (son of Thomas R & Jane Lace) who married Ann Skelly. In 1851 they were in Cronk Glass, Andreas.
Nor John also bapt 1816, the son of John Radcliffe & Catherine Howland, who died without issue.
There was John Lace Radcliffe son of John Radcliffe & Elizabeth Teare bapt 20 May 1813, from the family of parish clerks. Carol may remember what happened to him.
