Henry John Sheridan Barron
Acting Able Seaman in the RNVR in the First Benbow Battalion (BENBOW005) Service Number London 7/3350 awarded the 1914-15 Star Victory Medal, British War Medal. A number of Kitchener P/301 also appears and his forces war record is number 3835114. He fought in the defense of Antwerp and was taken with the few surviving by Colonel Henderson over the border to Groningen in Holland. They were interred in the English Camp (Timbertown) for the duration of the War. He is shown in the records of the Benbow Battalion but his surname may be recorded as Barrow and a book has been written about the English Camp by Menno Wielinga in Dutch. I have photographs signed by him where he appeared in theatrical productions in the Camp, Menno has his name in corresponding programmes of the shows.
I see the original poster has already found him, but if anyone else is interested he's here: https://livesofthefirstworldwar.org/lifestory/6104271
