I find I do have a reference (modern) to a house called 'The Raggatt' on Glenmaye road (ie main road) in Patrick village - it is very likely however that it was named after the estate up the road towards Peel (I also find that the offical address I have for the raggatt places it in Peel, German - though to be honest I always thought it was on the Patrick side of the Neb (maybe the postal address is subtly different)
