We present 41 trigonometric parallaxes of 37 stellar systems, most of whichhave proper motions greater than 1\farcs0 yr$^{-1}$. These are the firsttrigonometric parallaxes for 24 systems. Overall, there are 15 red dwarfsystems and 22 red subdwarf systems in the sample. Five of the systems aremultiples with directly detected companions, and we have discoveredperturbations caused by unseen companions in two additional cases, the dwarfLHS 501 and the subdwarf LHS 440. The latter system may eventually provideimportant dynamical mass points on the subdwarf mass-luminosity relation. Twoadditional stars of note are LHS 272, the third closest M-type subdwarf at adistance of only 13.6 pc, and LHS 2734AB, a high velocity subdwarf binary with$V_{tan}>$ 700 km/sec, which likely exceeds the escape velocity of the MilkyWay. We also report the first long term variability study of cool subdwarfsindicating that cool subdwarfs are less photometrically variable than theirmain sequence counterparts.
