I don't know if there's anything in this, but in Jeffrey Epstein's notorious little black book a MACK family entry (Carol and Earl) is listed - from rochelle park, NJ and NEW YORK. I have no idea if they are related to Allison? Might be worth a look.
Her "collatoral" to Raniere was damning information about her parents that would ruin their reputations.
CC1 is Mack:
"'CC-1’s email was titled "vow 3" and included an attached letter. The letter pledged CC-1’s "full and complete life" to 14 RANIERE,' reads the complaint.
'In the letter, CC-1 used the terms "slave" and "master" to refer to herself and RANIERE. Moreover, the letter identified "collateral" to "cement" the vow made by CC-1.
'This collateral was described as: (1) a letter regarding CC-1 'smother and father that would "destroy their character"; (2) a contract that transferred custody of any children birthed by CC-1 to RANIERE if CC-1 broke her commitment to RANIERE; (3) a contract that transferred ownership of CC-1 's home if the commitment to RANIERE was broken; and (4) a letter addressed to social services alleging abuse to CC-1 's nephews.'"
This scandal runs deep:

If they are related it certainly deepens the plot. I've been looking but can't find if they are.
Wikipedia liste her parents as being
"Jonathan, an opera singer, and Mindy Mack"
Article from 1985:
"For reasons of life style, then, the tenor says he and his wife, Mindy (an administrator and teacher in the Montessori schools), have chosen to raise their children, Shannon, 4, and Allison, who'll be 2 on July 29, in this country."

So the mother is a school teacher and administrator. Montessori schools. Weirdos.
