We present a 14 year photometric study of one confirmed and one suspected variable star in the field of the TeV blazar 1ES 1959+650. Both stars have previously been used as comparison stars for the blazar 1ES 1959+650, and are identified as star 3 and star 5 by Villata et. al. (1998). Star 5 is also known as MM Dra and is an eclipsing binary of the EW UMa type, exhibiting evidence of the O'Connell effect. A very recent calibration based on Gaia parallaxes suggests a distance of about 600 pc. Star 3 is a variable star of undetermined type and a color analysis suggests it is a late K or early M type star.
