Hi Joanne,
You seem to be a long time searching for this marriage. I did look up
Rosemary Ffolliot's index a while ago to see if it was listed in any
newspaper around the time ( this index covers 1780's to 1830 approx) no
reference to your Mary Cudmore.
I think maybe your best course of action now would be to contact the
Canon in St James church. She is very helpful and holds many original
records there. Contact ref
http://www.mallow.cloyne.anglican.org/contact/ It is possible that Mary and Samuel married at Ballyclough which is closer to
Longueville than Mallow. There are a few possibilities, Clonfert, Ballyclough,
Newmarket, Dromagh ( for which there are no remaining records) Millstreet ( I have come across a few Cudmores in Millstreet) and of course St James Mallow.
You would have to give a donation towards the search but certainly might
produce a result and probably the best option at this stage.
