Hello all. I know I am somewhat on the right track but still relatively new to detailed research. I have a 2 clasp QSA, Paardeberg/Relief of Kimberley to a Gordon Highlanders lieutenant. I have reason to think he was in the GH Mounted Infantry company. I have looked at the medal rolls for 1st Bn and the clasps are correct. I also looked at the roll for Details/23 MI but he is not there which makes sense since he is already on another roll. There is an annotation on his QSA entry that he was with "details 1st Bn." I have also looked at the Spink British Battles and Medals and for the RofK clasp it shows Detachment GH Mounted Infantry.
Therefore, although I am leaning towards him having been in the MI but not 100% certain. I have much paperwork related to him and there is no reference there. Any assistance and/or advice is welcome and appreciated!
