At the same time, the Boko Haram terrorist network is negotiating over the students' fate and is demanding an unspecified ransom for their release, a Borno state community leader told The Associated Press.
He said the last night message from the abductors also claimed that two of the girls have died from snake bites.
The message was sent to a member of a presidential committee mandated last year to mediate a ceasefire with the Islamic extremists, said the civic leader, who spoke on condition of anonymity because he is not authorised to speak about the talks.
She said the parents' information about mass weddings is coming from villagers in the Sambisa Forest, on Nigeria's border with Cameroon, where Boko Haram is known to have hideouts.

"The latest reports are that they have been taken across the borders, some to Cameroon and Chad," Aliyu said. It was not possible to verify the reports about more than 200 missing girls kidnapped in the northeast by the Boko Haram terrorist network two weeks ago.
Outrage over the failure to rescue the girls is growing and hundreds of women braved heavy rain to march yesterday to Nigeria's National Assembly to protest lack of action over the students. Hundreds more also marched in Kano, Nigeria's second city in the north.
"The leaders of both houses said they will do all in their power but we are saying two weeks already have past, we want action now," said activist Mercy Asu Abang.
Nigerians have harnessed social media to protest, trending under the hashtag #BringBackOurGirls.
There also has been no news of 25 girls kidnapped from Konduga town in Borno state earlier this month.
A federal senator from the region said the military is aware of the movements of the kidnappers and the girls because he has been feeding them details that he has gathered on a near-daily basis.
