Amazing luck David that I saw your post's mention of the macausoul.com/photogallery site; I have been searching (from here in Australia) for years for a Ballavagher Farm in this locality and this may have hit the jackpot.
Can you advise a contact for the photographer behind those pics of the farm and/or would appreciate any other information available on this Ballavagher property regarding family who have used it. Thank You.
