Arising from something I posted on Rum Ration about ships' logs, I thought I would mention that the National Archives at Kew holds series of battery monthly pay lists for the RA. With these, and with luck, you can trace individual gunners from way back (my target served 1830s-1840s), what their rank was & what their pay etc. DO NOT try to order copies on line as they are LARGE docs and would cost a fortune to have copied. But if you have an RA OR forebear and have time to visit and work through these, it's a data goldmine.
