In Jain tradition, the Tirthankaras are mainly known by their names and gotra/kula, not by modern family surnames.

If you mean Tirthankara names beginning with “V”, the main ones are:

• Vasupujya Swami
• Vimalnath Bhagwan

If you mean families/lineages associated with Tirthankaras starting with “V”, these are generally described as royal clans and gotras, not common family names.

If you want, I can give a full list of Jain Tirthankaras whose names start with V.
