Query: Fundamental Group for some Cuspidal Curves   We construct a family of plane curves as pull-backs of a conic for abelian
coverings of P^2. If the conic is tangent to the ramification lines one obtains
a family of curves of degree 2n with 3n singularities of type A_{n-1}. We
calculate the fundamental group and Alexander polynomial for any member of this
family and for some deformations of it.
