Possibly William, but it's very difficult to make out.
I tried enhancing it, but it was no clearer.
Maybe one of the photo whizz people on here can do better.
You could always write to where the record is held (Pembrokeshire RO?), and ask them if they can tell what it is from the original register.
I've done similar things before now. I've always found RO staff very helpful.
These black and white films, on the whole done many, many years ago, don't cope very well with some registers.
