• In Jain sources, Vinami is described as a cousin of Rishabhanath (Adinath). He is part of the early Ikshvaku/Nabhi line and is mentioned as one of the kin related to Rishabhanath, sometimes noted together with Nami as cousins who later wield special vidyās (knowledge/powers). ( wisdomlib.org)

• A common thread in these accounts is that Vinami (and Nami) are part of the same lineage connected to Rishabhanath and are associated with the early spread of certain vidyās within Jain lore. There can be slight variations across texts (Digambara vs. Śvetāmbarā), but the basic point remains: Vinami is a relative of Rishabhanath, not a son or direct descendant, and is linked to the vidyā tradition in early Jain narratives.

If you'd like, I can look for a specific text reference in Digambara or Śvetāmbara sources.
