New or refined visual orbital elements are presented for four double stars (HR 266 AP, 88 Tau AP = CHARA 18, eta Ori AB = McA18, ADS 16904 AP = CHARA 149) that are members of multiple systems. Relative photometry and positional speckle measurements with the 6-m telescope and published radial-velocity data for the stars are used. Photometric data and parallaxes from the Hipparcos catalogs are also taken into account. New physical models are proposed for multiple systems.
