Well, I honestly think they are typing errors, as it probably is in the question here. (I know there is no point in asking). Yamanamanda IS an Indian name. It is used by the Kowdenya Gothram of the Andhra Kshatriyas from Poduru village. By the way they are Vaishnavites, as someone called Srinivasa would be, so that is consistent with my theory.
