|The following is based on Van Buren and has not been confirmed by canon sources.|
Tiaret Van Graff was the matriarch and head of the Van Graff family, which was going to be featured in Van Buren. She directly opposed Orville Wright and his family over control of New Reno's caravan and drug trade, which Redding depended on, but could not openly fight him, as the NCR would wipe out the victor.
Tiaret is never mentioned by name in Fallout: New Vegas, but is mentioned through dialogue as "momma" with Jean-Baptiste Cutting and "mother" with Gloria Van Graff. According to Jean-Baptiste, she had many husbands, although she gave Jean his surname to remind her of his father.
