I have checked the one who died in 1840, I ordered the death certificate and this Thomas is the infant son of George & Maria of Garboldisham.
There is another Thomas Batley who died in 1840 in Blofield District, but I am fairly certain that this was a Thomas Batley who lived in Thorpe and his wife was Susanna Emery.
Another one in 1844, he was the brother of the George above. Also from Phoebe's death certificate she was a widow at her death in 1843 so Thomas had already died pre 1844.
I found out that Phoebe's maiden name was Chilvers from the parish records for Fersfield that are on the FreeREG website they have been transcribed up until 1812. Phoebe was married to a Thomas Bobby on 25 Mar 1799 at Fersfield,
Bride Forename Phebe,
Bride Surname Chilvers
Bride Parish Fersfield
Bride Condition Spinster
Thomas & Phebe had one child James born at Fersfield 7 Nov 1801. Thomas Bobby also died in 1801 in Fersfield.
There is also a baptism record for a Phoebe Chilvers in Fersfield 20 Jun 1780 - Mother Elizabeth Chilvers in the notes section it says Base Born. Phebe was 63 years when she died (from her death cert) so the dates seem to fit.
Thomas Batley was also a widow at his marriage to Phoebe, he was married to an Elizabeth Mickleborough/Mickleburgh and she died in 1810 in Fersfield. They had 2 children Mary & Diana. (These records were also on the FreeREG site)
I would like to try and find Thomas's death record in case there is an age at death which would give me some idea of his year of birth. There were a lot of Batley's born in Kenninghall, Norfolk, which is close by to Fersfield and I think that my Thomas Batley may have come from there as there is a Thomas Batley born in 1766 in Kenninghall to parents Thomas Batley & Sarah Hammond. Probably hard to prove but will keep digging and see what I can find!
