We consider holomorphic families of Kleinian groups parametrized by a domain of

 the complex plane. We do not assume that Kleinian groups are finitely generated. 

If the domain is simply connected and those groups are isomorphic to each other, 

then Bers showed that the family is obtained by quasiconformal deformations.

 In this talk, we consider such families parametrized by a non-simply connected 

domains.
