  In this article, we prove that for several one-dimensional holomorphic
families of holomorphic maps, in the parameter plane, there exists a local
piece of a curve that lands at a given parabolic parameter, in the spirit of
well-known results about the quadratic and the exponential families. We also
show that, under some assumptions, this general result partially answers the
existence and landing questions of ray structures in the parameter planes for
holomorphic families of transcendental entire maps.
