There are some Notts and Derby experts on the Forum, so hopefully one will see this post and answer your questions more fully. However I will try and answer some points.
1) I believe that the second line territorial battalions were originally formed as feeder battalions to the first line battalion, in this case the 1/6th Bn. In other words they trained and held new recruits, who would then be sent as replacements for casualties in the 1/6th Bn. I am not certain that they had any other committments than this at that time.
2) As the war progressed and more battalions were needed at the front, then many of these second line battalions were sent to France as active service battalions.
3) I think that the whole battalion would have gone to Ireland, but I am not certain about this!
There is a good chance that your man served in Ireland but it is just possible that he either transferred to the 2/6th from another battalion after they arrived in France, or went out as a replacement having not served abroad previously.
If you know where he came from then it may be worth looking in the local newspaper around the time of his death to see if he receives a mention. If you can find an obituary then this will more than likely tell you where he had served and, or, when he went overseas.
I hope that this is helpful.
Good luck with this.
