Her immediate family should immediately lose all government benefits and be deported as soon as she is convicted. When her prison term is done send her back to the dung hole of Somalia too. Her mosque should also lose tax exemption.
In the aftermath of the American Revolution, practices such as what you're suggesting were categorically rejected under the idea that all Individuals are created equal and endowed with Unalienable Rights.
This woman is an individual who is (apparently) guilty of some very serious crimes—and she's well on her way to a lengthy prison sentence.
But rather than fallaciously attaching Guilt by Association to individual members of her family to achieve the goals you suggested, the legal method would involve each of them being convicted of similarly heinous crimes, pursuant to Constitutional due process.
The idea of this woman's church losing its tax exemption is limited by the First Amendment. I suppose that Timothy McVeigh's church—if he even attended one—would similarly be liable for that sort of sanction, if the policy you're suggesting were adopted in America. Such policy would doubtless run afoul of the First Amendment—unless, of course, it could be proven that the church was preaching sedition.
