Hello Di - first thing I need to say is to 'beware of the Ancestry Trees'! In fact be very careful with any Family Tree that you find online and make sure that you check out the details for yourself.
I have mentioned this many times throughout this site but it never hurts to keep reminding people.
In this case the information about the Phillack burial is correct.
My initial information on the baptism of your Jacob came from another researcher many years ago but I have just checked the St Ives register and can confirm that he was baptised on 15th May 1722 at St Ives as the son of Richard Curnow and Blanch his wife.
The earlier records have not been transcribed for the OPC site as yet and it may take some time as I know many parts of the registers are extremely difficult to read.
The known children of Richard and Blanch are:-
Matthew bp. 29th December 1714 St Ives
Jane (baptism not found)
Sibella (baptism not found)
Richard bp. 2nd January 1719 St Ives
Jacob bp. 15th May 1722 St Ives
Peter bp. 5th September 1725 St Ives
I have just copied all of these from the St Ives Parish Register but except for Jacob they can also be found in IGI.
But a word of warning with IGI also.
There are three Batch Numbers for the early St Ives records - P014781, C023291, C023292.
P014781 - The Transcriber(s) for this Batch Number did not transcribe the dates correctly for events that occurred January, February and March prior to September 1752.
Prior to this date the Julian Calendar was in place and the Year commenced on March 25th and ended on March 24th. So any events for January February and March would have been at the End of the Year.
Instead of transcribing these dates 'as written' the transcriber(s) added 1 to the Year to reflect the Gregorian Calendar and this can (and has done) cause a lot of confusion!
Example - date written is 15th January 1730
Transcribed as - 15th January 173
1Many people using 15th January 1730/1 to indicate this is an 'Old Style' date which is fine but it should NEVER be written as 15th January 1731 as this only serves to perpetuate an error. Why?
- Because the next person in the chain may well think that this is the date in the register and they then record it as 15th January 173
2!
Believe me - I have seen all of the above!
The other two Batch Numbers appear to have been transcribed correctly so just be aware of the problem with P014781. And unfortunately it is not just St Ives where this has happened.
And now back to the stuff you really want information about!
The fact that no marriage has been found for Richard and Blanch and the fact that baptisms for the two known daughters have not been found suggests the possibility that these events may have occurred at Towednack where Richard had been born. There are many gaps in the Towednack registers between 1704 and 1720.
The Will abstract you found is the correct family and you will note that Richard does not name his wife whom I believe to be the following:-
Blanch Curno of St Ives buried October 12, 1726 Morvah
That should help kick you along a little bit.
