Thank you for your reply. However, in the list of Glamorgan's listed parishes on the 1911 Census Returns (they aren't indexed on Ancestry at the present time), there is no Michealstone Higher, Lower or Baglan Higher. I've gone through all the Glyncorrwg entries, and all the Llantwit Lower entries, thinking that either Baglan or Michaelston/s could have been there, but I have found nothing.
