Below are a couple of what I believe to be the correct records you are seeking. If you search the Parish Records you will find that there are few possibilities for the baptism of Samuel HAYNES (HAINES) who married Mary FROWEN.

I have not done a complete search for all the people but these should get you on your way.

Hi,
I've been using this site for a while, but recently I've noticed some names are now missing from the Parish Records. I have found some people who I believe "may" be family members but they have disappeared. Some of the names are Samuel Haines born 1786 in Huntley, Gloucestershire. William Haines born 1751. Samuel Haines born 1720 both from Huntley.
I've tried searching for them by year, name, spouse, location, everything, but they don't seem to exist anymore! If you could shed some light as to why this might be I would be very greatful.

These are all the details I have for the names I can't find:
