Looking for Kings of Herefordshire UK

I have managed to track my mother's family, Kings, back to Robert Kings who married Sarah Baylis on 25 May 1778 in Eastnor, Herefordshire, UK. I have not been able to find his birth or any other data about him. The family seem to have been in Herefordshire continually from that time, and Eastnor was such a small place it is likely they were in that area before 1778. Any help would be appreciated.
