Thank you everyone for your help. I can't understand why I wasn't getting the results when I searched under Browne & Brown. But they are found now which is great and I also found their eldest child's baptism with the same wrong spelling of Bunnet.
Yes the marriage of Sarah Bunnett to John Gowen is the sister of John and yes the other baptisms belong to him, up to 1812 they all had the entry regarding Mary being a spinster but those who came after didn't have that note, however now I have viewed the baptism entries (thank you for the directions) I can see it was the practice of the Church to privately baptise the children and record the mother's status at time of her marriage. I've not seen that before.
I've had all these names for several years but no way of confirming them as only source was IGI member on the old data base, I've only just found Free Reg in the past few months so great to have confirmation now.
Whilst I found the baptism image after a bit of jumping around, the data base was Archdeacon records (see below) which had nearly 200 images not 67.
These were my steps but maybe I am selecting the wrong database because I can't find one with just 1754-1806 and from what BumbleB is saying, narrows it down even more to just 67 images.
1. Browse by location - selected United Kingdom & Ireland
2. Place - narrowed it down to England and got the following for Norfolk:
Archdeacon's transcripts 1600-1812 (where I found the baptism)
Bishops Transcripts 1685-1941, which gave me Norfolk, when I click on that I get Archdeaconry of Norfolk or Archdeaconry of Norwich. Each is then broken down into years.
Marriage Bonds 1557-1915 (which is alphabetical I think but doesn't start at A)
Parish Records, which is the one you usually search through.
So am I missing a link somewhere. Mind you knowing now that the images are on-line is going to be very distracting from all things "Life"
Thank you again
Regards
Debra
