Calswimmer - very happy to be of help.
Regarding the 1861 Census information for Clevedon, Somserset - I think I 'might' have deciphered the name of the visiting
? Mary Thomas.
Another look now indicates that the first name 'may' be GEORGIANNA - if that is any help. (I cannot be absolutely certain but that is what it now looks like.)
Now - looking at your latest notes I think I have something more to add.
But it is now becoming even more confusing to me.
1. SALLY d/o Thomas and Catherine Bohenna bp. Lelant 28th December 1800 (IGI)
2. From Lelant Online Parish Registers (Marriages)
13 February 1830 by banns
Isaac Penberthy of the parish of St. Ives
Susan Behenna of this parish
Witnesses: John Penberthy, Joshua Bohenna
3. Sister Jane was baptised at Lelant 27th December 1811 (IGI)
4. Jane w/o John Victor was aged 46 in the 1861 Census (bn. c. 1814/5)
Possible solutions - 'SUSAN' - depending on the handwriting, this name could be interpreted from a name that actually reads SARAH and, given SALLY is a commonly used name for anyone called SARAH, then the problem may not be so great.
'JANE' - is interesting.
The Census shows her as five years older than her husband but, unless the Jane of 1811 died and another Jane was baptised to the family ........
In 1851 Jane's age was also consistent with a birth of about 1814/15 and John Victor's age was also consistent with the 1861 Census.
At this time they had daughter Sarah Jane (1) who had been born at Westbury, Bristol (their location in this Census).
And (I think you mentioned) in 1841 John Victor is a schoolmaster residing with the family of Isaac and Sarah Penberthy at St Ives.
*** There is something not quite right about this whole problem and I just cannot, at the moment, figure it out.
1. I cannot yet find the family of Thomas Bohenna in the 1841 Census
2. Jane (wife of John Victor) in two consecutive Census gives an age consistent with being born about 1815 and, in both cases, is about five years older than her husband. (States she was born at Lelant in both entries)
3. The Jane I 'know about' was baptised in 1811 at Lelant
4. Thomas Bohenna (bn. c. 1820) - I would say that there has to be serious doubt about his being the son of Thomas and Catherine Bohenna.
The know son of Thomas and Catherine (from my records the only son) was Thomas bp. at Lelant in 1799 at which time his mother (Catherine Curnow) would have been about 26.
The last (currently) know child of this family was Jane bp. 1811 at Lelant.
The Thomas Bohenna who came to Australia was born about 1820 at which time Catherine would have been about 48 or 49.
The next interesting point you have mentioned is that Thomas (Australia) named one of his children 'Joshua'.
Whilst searching the Census I found that about the only area this name was found in the Bohenna family was around Veryan and possibly Gerrans.
There are two many inconsistencies and anomalies creeping in here so I am going to have to come back and think about this situation at a later date.
I really need to look at this, and all other information, in the 'cold hard light of day' and see what I can make of it.
But there is certainly a problem here that needs to be solved.
