Formerly of

Hi everyone,



I came across the sentence below while reading the article from Reuter.

"If she cannot fulfill the guardianship duties, pop singer Diana Ross, formerly of the Supremes and a long-time friend, is nominated to be guardian of the children."



I understand that Diana Ross was one of the members of the Supremes, and I suppose that "formerly of the Supremes" is spelled out as "a former member of the Supremes" or as "a former part of the Supremes."



On a google search, I have found that the names of companies, music bands, places, etc. follow “formerly of.”



Is my understanding correct?

(A) In the case of companies, it means that the person worked for that company.

(B) In the case of music bands, it means that the person was the member of that band.

(C) In the case of places, it means that the person lived in that place, or that the person was the member of the local authorities (such as a diet member) located in that place.



Thanks very much in advance for your responses.
