Mass discoveries of variable stars by modern automatic sky surveys make it very important to determine accurate coordinates for all previously documented variable stars. For many "old" variable stars, no finding charts were ever published, and only rough coordinates were reported. Existing collections of sky photographs, however, make it possible to recover such "lost" variable stars. Here, we present our results on the recovery of nine "lost" variable stars: NY Cyg, QX Cyg, VW Sgr, GW Sgr, GZ Sgr, HK Sgr, HT Sgr, HU Sgr, and HW Sgr, using plates from the Maria Mitchell Observatory collection in Nantucket, Massachusetts. For the stars recovered, we present finder charts, accurate coordinates, improved classification, and light elements. In the case of HW Sgr, there is an indisputably variable star approximately in the published position, but the character of its variability is in complete disagreement with earlier data. Either HW Sgr was misclassified by the discoverer, or the discoverer's position for the star is in error and we have actually discovered a new variable.
