Burials in the parish of Holy Trinity, Forest of Dean

I am a descendent of the Marfell families from Ruardean/Ruardean Woodside and I have noticed that the burial register for a large number of my relatives is listed as "burials in the parish of Holy Trinity, Forest of Dean. I am trying to establish if the actual burials would have been at Holy Trinity, Drybrook or Ruardean.

Would appreciate any information regarding this query.
