The technique of ensemble averaging of mass tables is used to obtain a set of mass predictions based on the Garvey-Kelson relationships along with their intrinsic uncertainties. Predicted masses are presented for nuclei in the ranges 2 ≤ Z ≤ 109, 4 ≤ N ≤ 157, and 7 ≤ A ≤ 265. These predictions include also Z-rich nuclei whose values are derived from an extended symmetric mass relationship with phenomenological Coulomb corrections. However, Z = N = odd nuclei where Z ≤ 27 are omitted from the calculations. The standard deviations of the fit to masses that are known to better than 250-keV accuracy is 219 keV.
