As I discuss in this question, the Sri Vaishnava sect (of which I'm a member) is divided into two sub-sects, Thenkalai and Vadakalai. Both Thenkalais and Vadakalais have Mathams, similar to the Shankaracharya Mathams in Advaita. But a small number of Sri Vaishnavas, known as Swayamacharyas, do not belong to any of these Mathams. They're biological descendants of the 74 original disciples of Ramanujacharya, and for them a member of their own family functions as their Sri Vaishnava Acharya. For instance, my family is Swayamacharya family descended from Ramanujacharya’s nephew and disciple Mudhaliandan. But I think I may have found another descendant of Mudhaliandan. Let me explain.
One of the most popular Sri Vaishnava lecturers today is U. Ve. Velukkudi Krishnan Swami. I’ve long known he’s a Thenkalai, but I recently found out that his guru was the Sri Vaishnava Acharya Sholingur KKC Vedantachariar Swami: see this Wikipedia page and this tweet by Velukkudi Krishnan himself. Now Sholingur KKC Vedantachariar Swami was a descendant of Cholasimhapuram Doddacharya, a 17th century Sri Vaishnava Acharya descended from Mudhaliandan, most famous for getting Varadaraja Perumal, the Vishnu deity of Kanchipuram, to appear before him in Sholingur. (Cholasimhapuram is the original name for Sholingur.)
But my question is, does this mean that Velukkudi Krishnan is a Swayamacharya person descended from Mudhaliandan? Or did he merely decide to take a guru who happened to be a descendant of Mudhaliandan?
