We investigate the effect of external pressure on magnetic order in undopedLnFeAsO (Ln = La, Ce, Pr, La) by using muon-spin relaxation measurements andab-initio calculations. Both magnetic transition temperature $T_m$ and Femagnetic moment decrease with external pressure. The effect is observed to belanthanide dependent with the strongest response for Ln = La and the weakestfor Ln = Sm. The trend is qualitatively in agreement with our DFT calculations.The same calculations allow us to assign a value of 0.68(2) $\mu_B$ to the Femoment, obtained from an accurate determination of the muon sites. Our datafurther show that the magnetic lanthanide order transitions do not follow thesimple trend of Fe, possibly as a consequence of the different $f$-electronoverlap.
