Here is a simple, tradition-respecting overview: in Jain tradition, the 24 Tirthankaras are described with different details for caste, marriage, children, and their Ganadharas. Two key points to keep in mind:

• There are differences between Digambara and Śvetāmbara sources on some details (especially about Mahavira’s marriage).
• The “final birth” (the last life before renunciation/renunciation and keval Jnana) is treated in each line of tradition with its own text-by-text variations.

Brief answers (highlights; traditions differ on some points)

• Caste in the final birth: Most Tirthankaras are described as belonging to royal/warrior lineages (often labeled as Kshatriya), but there are variations. For example:

- Rishabhanatha (Adinatha) is described as a king in the Ikshvaku line (Kshatriya affiliation in many sources). - Mahavira’s royal birth is also described as Kshatriya in many texts; the Śvetāmbara tradition names Siddhartha as his father, a Kshatriya ruler of the Nāya clan. - Other Tirthankaras are likewise associated with ruling or noble lineages in various Jain texts; some later Tirthankaras are described in ways that align with their historic or legendary lineages rather than a strict varna category.

• Marriage and children:

- Some Tirthankaras are described as married with children (e.g., Mahavira is described in Śvetāmbara texts as having a wife (Yashoda) and a daughter (Priyadarshana/Anojja); Digambaras say Mahavira did not marry). - Others (like Rishabhanatha) are described as having wives and many children (Rishabhanatha is said to have two wives and numerous children, including Bharata). - Ganadharas are the earliest ordered disciples; the number and names vary by text, but the standard archetype is that each Tirthankara had a core set of Ganadharas who taught and spread his doctrine after kevala Jnana.

• Ganadhars:

- The traditional pattern in many Jain sources is that each Tirthankara had a group of Ganadharas (the foremost being the chief Ganadhara). The common teaching lineage is that there were multiple Ganadharas (often described as 11 key Ganadharas in Śvetāmbara accounts), though exact lists can differ by source and by Digambara vs Śvetāmbara.

Important note on sources

• Because there are genuine differences between Digambara and Śvetāmbara readings for several Tirthankaras (especially Mahavira) and because details like exact Ganadhar names can vary by text, it’s best to consult a specific text for each Tirthankara if you want precise per-Tirthankara data.
• If you’d like, I can summarize the exact details for a particular Tirthankara (e.g., Mahavira, Rishabhanatha, Neminath, etc.) as they appear in Śvetāmbara and Digambara texts, with the tradition-specific notes.
