We will present the results from common proper motion searches for wide low-mass stellar and sub-stellar companions to known tight binary systems. Observations were made with the 4m telescope at KPNO and the 31" NURO telescope at Lowell Observatory. The binary systems observed at KPNO are spectroscopic binaries, while the systems targeted at NURO are unresolved or partially resolved white dwarf-M dwarf binaries. We are testing recent simulations of star formation that predict that tight binary systems form by transferring angular momentum to a lower mass third companion. Any genuine companions will be able to serve as 'benchmark' low-mass stars and brown dwarfs. The central binary, particularly the white dwarfs, will allow us to estimate independent values of age and metallicity for the wide, low-mass companion. The candidates are primarily selected using astrometry, and then the list is refined with photometry. We present the candidate companions we have found to date and the future plans for this project.
