Misspelling - either record or gravestone
277793 Private James Finnagan - I've added a photo of his grave which reads Finnigan. Either the record is incorrect or the stone was incorrectly engraved. Hopefully if family members are searching they'll try alternative spellings.
Hello, it is possible that a spelling mistake may have crept into James' Medal Index Card - as you rightly say, CWGC record him as Finnigan, as does the Soldiers died in the Great War database. To ensure that both spellings will take us to the correct page, I will enter his name as 'James Finnagan or Finnigan.' Thanks for your help.
