My 7th great-grandfather Clement Uren appears to have written a Will on 7 Aug 1745 making his wife Elizabeth and daughter Tiberia the beneficiaries.
At the Cornwall OPC (Online Parish Clerk) site there are two transcriptions:
Forename Clement Surname UREN Date Written 07-Aug Year Written 1745 Parish Illogan Beneficiaries Elizabeth Uren (wife),;Tiberia Uren (dau) Document Notes Proved 17-Jul 1747 Transcriber
Forename Clement Surname UREN Date Written 07-Aug Year Written 1745 Parish Illogan Beneficiaries Elizabeth Uren (wife); Tiberia Uren (dau) Document Notes Proved 30-Sep 1754 Transcriber
The two transcriptions have different Proved dates of 17 Jul 1747 and 30 Sep 1754 respectively.
If not a transcription error, is there any reason why a Will might be Proved twice?
