Given that GALNET is text only, most people who are named in GALNET articles don't have faces that would be publicly recognizable, at least to us as CMDR's. For that matter the only people whose faces are readily recognizable to us are the powerplay faction leaders. This could imply that at least a couple Club leaders are found within their ranks.
From analysis of Premonition I derived the following Club membership list:
Infrastructure, male, the 'leader', technology (Li Yong-Rui)
Finance, female (Ana Quin, Sirius' Junior Vice President of Interstellar Logistics, or Patricia Spell VP of Sirius Finance)
Exo, male, thin & gaunt, exploration & non-core worlds (?)
Personnel, female, small & fierce (Felicia Winters, Fed Shadow President. Came to power rapidly through Halsey & Smeaton incidents)
Society, male, superficially jovial, steely glint, huge frame (not Patron Gerrun! ?)
From Premonition-Epsilon Eridani:“At just over ten light years from Sol, most of its visitors were of a Federal inclination”. If I’m correct in that Personnel was Felicia Winters then it would make sense for the two unknowns on the surface to be some of her staff who were also Club/Dark Wheel members. Elsewhere the book says that Zachary Hudson (Fed President) is being directly manipulated by the Group, so there would need to be Club/Dark Wheel staff in place to exert that manipulation.
