That would do it.
Try a local Museum or Heritage Society. They some times have
gravestone inscriptions in Journal form.
There is also a UK website but you must become a member and it isn't a cheap one, although they may have short term memberships.
They do have Ladytown Churchyard, gravestone inscriptions and also Celbridge, don't see Maynooth.
You will need to contact me for this as it is a commercial website and rootsweb/ancestry can remove any postings with
