The British South Africa Medal Roll is a record of all men who fought in the early Rhodesian Campaigns of 1830, 1893, 1896 and 1897.
If you believe any of your ancentors were there, send me a note of the surname and initials, regimental number and name of regiment I'll see what we can find.
If you don't have the military information, I'll see what can be done with only the surname and initials.
