In the ASCII character encoding, the hexadecimal number 61 is the letter 'a'. (Yes, it is lowercase.) 0x is just a notation that indicates a number is in hexadecimal, as opposed to decimal or binary.
Therefore, 0x6161616161616161 translates to the string "aaaaaaaa" (without the quotes or a null terminator).
The T is clearly visible and there's a single tail on the letter near the end of the name. Unless it's a foreign name I'm not familiar with, I can't think of any other names that would fit the bill.
