Hi Eric
It may be that 'sirim' is working on a local project to collect names for a database of those who served in WW1 and were from a local church/community/village etc. There are a lot of projects of this nature going on at the moment. For example, I am working on one trying to provide background information to names on a local War memorial. I hope that he gets back in touch as I am sure you could provide him with some good information on George Owen.
Just as an aside - men were not necessarily put into local Regiments (certainly not after the Pals fiasco). As the war progressed, men were generally put in Regiments that needed more men.
Kind regards
