are saitwal jain marwari decedents or any corelation with rajsthan perhaps

Short answer:

• Saitwal Jains are a Digambara Jain community, mainly found in Maharashtra. They are traditionally described as having Deccan (central-southern Indian) origins, with ancestors who were Kshatriya lineages that came to protect Jain sages and sacred places. Over time they split into two occupational groups (Setavala and Svahitavala), but today they are usually grouped as Saitwal Jains. They are not the same as Marwari or Rajasthan-origin Jain communities, though some Saitwal families later migrated to other regions, including Maharashtra. For details in Jain tradition, see the Saitwal origin discussion. ( jainknowledge.com)

Notes on correlation with Rajasthan:

• Rajasthan has its own Jain communities (for example Oswal, Bagherwal, Dugar, etc.) that have historical ties to the Marwar region and to Rajputana history. These are distinct communities with their own gotras, histories, and regional customs. There isn’t a direct, single lineage connecting Saitwal Jains to Marwari/Jain communities of Rajasthan as a whole. For context on Rajasthan-based Jain groups, you can see examples like Oswal, Bagherwal and other Rajasthan-linked Jain histories. ( jainknowledge.com)

If you’d like, I can share more about how Saitwal traditions differ between Digambar and Śvetāmbara practices, or point to specific genealogical or ritual differences.
