Sirjatavičius

Cf. Siriatãvičius, Sirijatãvičius, Sirijotãvičius, Sirjotãvičius (see). The origin is unclear. Perhaps these are glorified surn., which arose from the old double-stemmed pers.n. Si̇̀riotas ¹; for heart- see Si̇̀rgedas, for jot- - see (?) Jótautas. But cf. still (?) Sirutãvičius, Siratãvičius (see), Russ. Cиpятская (fem.) (CAМC IV 140).
