Google 'IGI batch numbers' One of the website suggestions you should get is headed 'Counties in England'. Click on this. Next select 'Hereford', scroll down to 'Brilley', click on the 'batch number', and follow the search procedure from there. There are transcribed parish records - baptisms to 1860. There are also marriages. Do not know how complete they are. Worth a try.

If is a Brilley in Herefordshire that you are looking for, then it is well outside of the area we cover.

The people on the 'Rootsweb Hereford Mailing List' will probably be able to help you.
