Checks show two of the group, Thomas Hamilton and Thomas Hope Morton, both killed in action are shown on ROH 1914-18 Netherton Coal Company Memorial at St Cuthberts Church which indicates they were miners with the Netherton Coal Company. Additionally, Thomas Hamilton was in the Northumberland Fusiliers (Tyneside Scottish) 23rd Regiiment and is listed in the book 'Tyneside Scottish' by Graham Stewart and John Sheen as being associated / living at Netherton.
Based on the above- and the information from Canny Lass - I believe East Row, shown in the Register of Enlistments was indeed at Netherton.

'what you say, I'd hazard a quess that East Row may well be First Street - if it is Netherton and if the year of enlistment is later than the date of construction of the 'modern' housing which included First Street. Prior to the 'modern' houses of First-, Second-, Plessey- and Third Street (built 1905-1909) all houses in the colliery area were Rows. The Francis Pit had Francis Row and South Row. By 1860 these had been renamed New Row and Cross Row.
The Howard Pit had Clifton-, Yard- and Howard Row.
It's not unlikely that people continued to call the modern housing 'Row' and it's not unreasonable to assume that First Street, given its name, was built in 1905'
Thanks to all who have helped to clear this up for me.
