  We investigate specializations of infinite families of regular Galois
extensions over number fields. The problem to what extent the local behaviour
of specializations of one single regular Galois extension can be prescribed has
been investigated by D\`ebes and Ghazi in the unramified case, and by Legrand,
Neftin and the author in general. Here, we generalize these results and give a
partial solution to Grunwald problems using Galois extensions arising as
specializations of a family of regular Galois extensions.
