Thanks to those who replied to my post.
Ken, I can't get into the 2 links you sent, probably blocked by FindMyPast. But I have a subscription to findmypast (which expires on Sunday!) so if you could direct me to where you found the material I will look myself. My John McG got married in Tralee in 1875. It says "Military" as his occupation. I wonder if he transferred to the Kerry Militia and is the guy whose pension application was thus delayed ...
However, in 1877, he is in Rochdale, Lancs., working as a shoemaker, but he would be over 40 by then. His son, my ggfather, also John McGovern, is born there, who also joined the West Riding Regt.
Could soldiers sign up at any time or did they have to wait until a recruiting campaign was under way? Thanks for all your help!
