The lawyer was a member of, and had advocated for, a Christian legal group that fights against same-sex marriage and for other conservative causes.
Testimony at the trial was graphic and wrenching.
As jurors watched recordings of various sexual encounters, the defendant averted her eyes from the laptop screen in front of her and dropped her head into one hand.
The final video, prosecutors said, depicted the woman having oral sex with her daughter.
Before introducing it into evidence, prosecutors had the girl's father — the defendant's ex-husband — identify the voices captured on tape. He wept uncontrollably after identifying the voices as his daughter's and his ex-wife's, and he left the courtroom before the tape was played for the jury.
As the tape played, its audio track filling the courtroom, the defendant clapped her hands over her ears and wept. The judge ordered the video stopped partway through.
"This goes on for quite a while," the judge said. He had prosecutors skip to the end.
In other recorded, expletive-laden phone calls to her parents in December, the defendant called her daughter a liar and blamed her for her predicament.
"This is not her daughter's fault. Tell her by your verdicts she should have been a mother," U.S. Attorney John Kacavas said in closing.
"The defendant was her pot pusher, her pornography producer and her predator," he said.
Defense Attorney James Moir had an uphill battle defending his client against the layers of graphic videos the defendant was alleged to have planned and produced. He said she didn't force or prompt her daughter to engage in the sex acts but called no witnesses.
"You can hate her. You can be morally outraged by what she did," Moir told jurors in his closing argument. "You can have these emotions, but you have to put them aside when you deliberate."
The jury signaled in less than an hour that it had reached a decision.
The daughter sat in the courtroom, apparently unnoticed by her mother, as the verdicts were read Thursday. Neither mother nor daughter showed a visible reaction.
"The evidence was pretty overwhelming," said juror Peter Evans, of Manchester. "She's going to deserve whatever she gets."
The mother has been behind bars since her arrest in November and faces at least 25 years in prison when sentenced in April.
