From the November 2016 Letter of Acceptance and Return:
Te{n_}{n_}ava{n_} Brahmam{a-}r{a-}yar. Name change from Julian Ó Néill.
Submitted as Tennavan Brahmamârâyar, this form of the name used diacritical marks inconsistently throughout the name. Using all diacritical marks, the name should be rendered as Te{n_}{n_}ava{n_} Brahmam{a-}r{a-}yar; without diacritical marks, it is Tennavan Brahmamarayar. As the submitter used some diacritical marks, we have registered the name in the form with all markings. The submitter may request reconsideration if no markings are preferred.
The submitter's prior name, Julian Ó Néill, is retained as an alternate name.
Nice 13th century Tamil name!
