I have a question about a string

[gaelcoral]

I was translating the strings from the reactivedrop_latam.txt file and I came across this string:
"asw_pda_owner_name_c_s_wiston_beaufort" "C.S. Wiston Beaufort"
What does the abbreviation C.S. mean? Since, unlike other strings, this one doesn't say anything.
The only thing that comes to mind is that it could be Chief of Staff.
