As for the names, this has been repeated plenty of times - for the last time just day before yesterday - see here.

As for the problem of not getting the provincial governor ancillary - it is possible that your FM already have the maximum number of other ancillaries (8). Try to pass those to aother FMs and see whether you get it

In my Roman campaign I often struggle with the incessant flood of various ancillaries my FMs are gaining, hardly having any slots open for them to gain provincial governorships or legion commands (I play with the Atraphoenix´s Extended Offices Mod).
