I have made up the sentences below.
(1a) I told Jack, "Yesterday, I visited ABC Store and met with the manager, John Brown." (1b) I told Jack, "Yesterday, I visited ABC Store and met with manager John Brown."
(2a) I told Mary, "Last week, I went to the Faculty of Science and had an interesting interview with the dean, Bill Jackson."
(2b) I told Mary, "Last week, I went to the Faculty of Science and had an interesting interview with dean Bill Jackson."
I am not sure if I need the definite article. Thanks for your help.
