Patty Hearst & Symbionese Liberation Army

I was looking up Stockholm Syndrome, of which Patty Hearst is a "poster-child". This picture below, on the left of Patty, her face looks like Madeline, from South Pasadena in 2001. Patty was born in the 50's. I wonder, if Madeline is her daughter.

In the second photo, taken Q3 2001, Madeline is on the far lower left in the red shirt. Standing behind her, and in the photograph depicted "above" her, is Diane, who looks like NXIVM's Pam Cafritz to me.

In the Wikipedia article about Hearst's abduction, the group responsible, called themselves: Symbionese Liberation Army. The summary states they're "educated" working class, who are against Upper Middle Class, HNW, UHNW. Marxism–Leninism idealogy that was birthed in Russia. This group, states they're "VANGUARD". NXIVM also touts their group as identifying with the same thing.

Is NXIVM a re-brand of SLA? Are the two the same, or an offshoot? Do you know?
