I have come into possession through a member of my family, who has no knowledge of the background, a Military Cross. It is assumed that it belongs to a family member, which one is not known, although the two known MC recipients' medals are already in my possession. A search of the London Gazette with all the usual names hasn't been successful. The isncriptione is for Messines on 7 June 1917. Is there any other online resource which would help me attribute this award? Surely there can't have been many MCs awarded on a particular day... can there?
