Judges in the city have sentenced Mariam to death and 100 lashes as the Sudanese court refuses to recognize her 2011 marriage to Daniel because her father was a Muslim.
The Justice Centre Sudan spokeswoman said: ‘When Meriam’s father left her mother when she was six he went to another part of Sudan and had another family.
‘Meriam did not know about this. She did not even know her father had died until many years after the event. Nor did she know he was a Muslim.
‘Meriam’s mother died in 2012 and by then she had still not heard from her half brothers and sisters.
‘There were years and years that went by when that side of the family did not want a relationship with her.
Meriam has also been sentenced to 100 lashes because the court did not recognize her marriage to Christian Daniel Wani, a naturalized U.S. citizen, who lives in Manchester, New Hampshire
