We establish the analogous results of level-lowering for Galois representations attached to p-ordinary Siegel modular forms with the same condition on their L-invariants. We place the Siegel modular form in a Hida Family and use the analogous formula of Harron-Jorza (2016) relating logarithmic derivatives of p-adic functions interpolating Hecke eigenvalues to the L-invariant.
