Medals to the Commander in Chief's Bodyguard - by: Stu C in C

I have 2 medals to this Regiment / Corps purchased 10 years apart. Having looked on this site, I am worried about the clasps on the 6 clasp medal as the top three are in the wrong order. Is it possible that clasps were attached in the wrong order or should I be worried about the genuineness of the clasps awarded.?

25493 Trooper William Kitchen (appears as Kitcher on this site.?!)

The clasps from bottom to top are : CC, OFS, Tr, South Africa 1901, Witt and Wepener.

Can anyone give me some advice on the clasps and indeed the surname.?

Thanks.
