We just returned from New Ross and are working with the St. Mary's University in Halifax NS, They are looking at what we found at New Ross and we hope to go public next week.
Did you show them proof of a foundation that was needed to support a castle the size you are claiming?
"For stone built castles the foundations would, wherever possible, been built directly onto the bedrock. The builders would dig down to the rock before leveling it to create the strongest possible foundation. The stones for the walls would be laid directly onto the bedrock. If there was no suitable bedrock or it was too deep, then a similar approach to that used today for buildings would be used. The builders would dig a deep and wide trench, then fill it with rubble that was packed down as firmly as possible to create a solid foundation. The wall stones would be built on the compacted rubble."
I highly doubt they dug down to bedrock in New Ross since I believe it is well over 100' in that area.Since you claim to have located the layout of the castle it is easy enough to drill down until you hit the subbase on which they started laying the wall rock.
No foundation = No Castle
It is possible although unlikely they dismantled the castle and moved it to another location.A source for rock suitable for building was a main factor in choosing a site on which to build a castle.Transporting the rock to the building site was actually one of the hardest and most time consuming jobs.
It is even more unlikely they would take time to also remove the foundation and backfill.Even if they did they could not do so without leaving evidence of the previous excavation that a simple core drill would expose.
Building a 13th-Century Castle in the 21st Century - The Atlantic
There are some very good photos in this link that show some stone work being done TODAY while building a medieval castle.To put it simply evidence of this work would be everywhere at the site not just a couple left over cut stones laying in a field.It would not be hard at all to prove if it had actually existed.
Ley lines and a vortex drawn on ancient or recent maps prove nothing.....I could sit down now and draw some lines and create a vortex on a map that intersects over my house.
Underground voids will not help your case either since underground waterways are naturally occurring in this area.
Anything found by dowsing will not get a second look from experts.
Artifacts or relics will not help prove the existence of a castle either and only a very select few will prove that Templars were ever on site.
You seem frustrated that officials wont come to New Ross after they have already looked at the site and dismissed the idea of a castle once standing there.It is common sense it will take even more definitive proof to get them to change their mind.
* I saw a construction project come to a stop because a pile of rocks were thought to be some type of Native American burial mound by an inspector.They had grown over in grass and once the construction crew started to move that pile of dirt it was found to be actually a pile of rocks.Pretty clear it was rocks removed from the field that it was along side but the inspector was adamant it was some type of ancient burial mound and needed to be examined by experts.Long story short it was not a burial mound,the cost of delay was paid for by the inspectors company and that inspector does not work for that company any longer.
Moral of that story is look at the simplest explanation first and then move outward if you don't get the answers you need.Starting out in left field is not the easiest way to get to first base.
Anytime Tom in Ca, anytime. 
you will have to wait until we start digging this spring for answers. Then all of the truth will come out.
