Pam,
Thanks for your interest.... I have a great interest in the NF in WW1, but my (pretend) coat of arms and name interests will give you clues that my interest lies in the 24th, 25th, 26th and 27th battalions, known as the Tynside Irish.
A "labour of love" of Bob Balmer, a local historian connected to Blyth Public Library, was to log all WW1 enlistments from newspapers etc. His scope was wider in that he covered all regiments, but narrower in that he covered only the Blyth area.
I have spent many frustrating hours in the National Archives at Kew, looking for individual NF soldiers and in the "war diaries" tracking the daily movements and actions of NF battalions (e.g. 24th and 25th)
I have also rubbed soldiers with folk in the Newcastle Local Studies library, who were logging WW1 enlistments from Newcastle newspapers. ( and further afield, as many Sunderland etc folk joined the NF)
Good Hunting
