I have undertaken this piece of research to know more about the place I hail from. I have presented below the little information I could gather about my roots.
The people of Serankulam are linked with the towns of Karappangadu and Selperi. Once upon a time, 7 devoted Sri Vaishnavas from Kooram and Kidambi villages of Kanchipuram set-off on a pilgrimage. On one nightfall, they stopped at the place now known as Karappangadu. That night, they had a dream – in which the Lord directed them to an anthill (marked by a flying Garuda) in which they were to find a deity. The Lord directed the Sri Vaishnavas to build a temple and chant the Divya Prabhandam for him. Thus, the town of Karappangadu was formed.
As days went by, the families from Karappangadu settled in the near-by areas. They got settled in Peravurani, Nammankurichi, Idaikadu/Puliyakkudi, and Serankulam – which came to be called “The Pancha Gramams” along with Karappangadu.
So in Serankulam, you expect to find Iyengars from Kooram, Kidambi, Karappangadu and Selperi.
Route to Serankulam: From Mannargudi bus stand, there are buses plying every 1:30 hours to Serankulam. Alternatively, one can take any bus bound to Muthupettai that goes via Serankulam Pillayar temple. Please note that there are two routes to Muthupettai and hence it is worth clarifying with the bus conductor beforehand. Else one can take an auto from Mannargudi to Serankulam, which is expected to cost Rs. 100.
