Dear Venkataramanji,
I think Shankaranananda and Vidyashankara are two different persons. Historically Swami Vidyashankara Tirtha was the guru of the Kudali Shringeri math, and when Malik Kafur attacked Karnataka, in the very beginning of the 13th century, the Swamiji had to leave Kudali Shringeri and escape to the Kanchi Kamakoti Math and he was heartily welcome there, and he was offered the Mathadhikari position there. After Malik Kafur went back to Delhi, he killed his boss, the Khilji king, and married khilji's second wife, and then Malik Kafur himself was beheaded by Khilji's son from his first wife and all these happened probably in a couple of year or less. The situation in Kurali Shringeri became normal and later on Vidyashankara swami sent back his disciples Vidyatirtha Swami as the Mathadhipati of the Kudalui Shringeri Math and his another disciple Swami Vidyaranya started another math in Hampi. Later on Swami Vidyatirtha shifted to New Tunga Shringeri and when he passed away Swami Vidyaranya became the Mathadhipati of the Shringeri math.
The things were very different eight centuries ago and there was great brotherly relationship between the Shringeri math and the Kamakoti math but eventually and unfortunately that great britherhood seems to have disappeared. Sureshwaracharya who was the first mathadhipati of the Dwaraka math, appointed a successor to him in the Dwarka math, and he himself took over the Kanchi Kamakoti math, when Adi Shankara Passed away. Later on when the Hastamalaka Swami, also known as Prithvidhara Swami wanted to leave Kudali Shringeri and go to the Kanchi Kamakoti math, Swami Susrasharacharya himself shifted to the Shringeri math. However for weird reason, all these great friendly changes in these mathsin those old days, are frowned upon by the later generations in these maths.
I only wish a new mathadhikari would appear in any of these maths and he would succeed in restoring the friendship between these maths , which prevailed in the good old days, and I also hope that the Shringeri math would accepts the truth that Adi Shankara was born in 509 BCE. The Rajatarangini gives the proof that Adi Shankara did visit Kashmir in the 5th century BCE, and Shringeri math will never be able to ignore that truth, however much the present management of the math tries to do.
