We present a study of Sm$_3$Sb$_3$Zn$_2$O$_{ 14}$ (SSZO) through magnetization and specific heat capacity $C_p(T)$ measurements. SSZO contains well separated planes of Sm$^{ 3+}$ magnetic ions on a Kagom\'{ e} lattice. Though our magnetic susceptibility (where the data are limited down to 2\,K) does not show any anomaly, the $C_p(T)$ data which have been taken down to 0.35 K reveal a broad maximum at $T\sim1.5$\,K followed by a sharp peak at $T\sim0.5$\,K indicative of short-range correlations and long-range order, respectively.
