  Let $\mathcal A$ and $\mathcal B$ be unital rings and $\mathcal M$ be a
$(\mathcal A, \mathcal B)$-bimodule, which is faithful as a left $\mathcal
A$-module and also as a right $\mathcal B$-module. Let ${\mathcal U}={\rm
Tri}(\mathcal A, \mathcal M, \mathcal B)$ be the associated triangular ring. It
is shown that every additive generalized Jordan (triple) higher derivation on
$\mathcal U$ is a generalized higher derivation.
