Under which law? If you're talking about English common law, widows of an intestate only inherited a life estate in their dower, and any claims under her dower rights were extinguished upon her death. In the case you're talking about, I think (and depending on any superseding statutes in that jurisdiction) the rights of the brother's widows would depend on the terms of their wills, if any. Dower only applied to real estate acquired during the lifetime of the husband, so she would not have dower rights to real estate "inherited" after his death, _but_ (after 1540) it was possible, though rare, for widows to inherit a permanent (fee simple) interest in real property by testament. That was fairly exceptional though, so in most cases, and in the case of intestacy, the widows wouldn't get anything out of it. Later on, most Anglo jurisdictions changed the laws of succession so that surviving spouses inherited some specified portion of property with full legal rights, in fee simple, but in earlier times, widows' property rights could be pretty thin.
