Would this be your man 3/4 of the way down column 4. http://newspapers.library.wales/view/4114868/4114871/40/
A search throws up references to bandmaster William Howells of Clarence Rd, Llandilo being the father with another son William awarded the military medal.
Edit: The medal card for Private. Henry Howells 4152 Welsh Regiment would appear be a good match for this man given the references in the welsh papers to the Dardanelles, a reported promotion to Lance Corporal, plus the personal recollections.
The newspaper report at first I was dubious as William was a stonemason. However, my cousin informs me William was also a musician so this could be correct as the last record I have is 1911 Census and who knows what happened up to 1915. Comparing the picture in that report with the only photo I have that includes him that was taken in 1944 does show a marked similarity so I am now 80% sure it is him. I shall now go to the Military record to see if any more details correspond.
Thank you very much, most appreciated.
