Barbara,
Firstly, welcome to the best place there is.
Bedminster is in Somerset so that forum may be able to help you.
However, in my list of LDS Batch numbers at
http://www.rootschat.com/forum/index.php/topic,275211.0.html you will find some batches extracted from Bedminster church records. One might give the answer to your query.
Regarding searching the batches, use the alternative method which can be the easier option. (Added - you will have to give location of course!)
Regards
Chas
P.S.
I've checked Batch C001765 without entering a surname and all the contents of the batch were given. The years covered include 1805 but no CARPENTERs are to be found.
This can be because
1. They were not baptized (at least not in Bedminster)
2. They were Roman Catholics (No LDS films of RC records for Bed')
3. An LDS member has "used" the info and the details have been deleted from the batch. Their presence as submitted entries in the IGI does not mean they were once in the batch and a search of other doc's is required.
Have a look at the LDS library catalogue for details of LDS films available for hire at LDS FHC's.
