Following the 1960-1996 civil strife, separated Guatemalan siblings have now reunited thanks to Facebook.
Ofelia, Avilio and Elsira Funez Velasquez had their tearful reunion at the headquarters of the Mutual Support Group, an activist with the social group, Enrique Barrera, said.
Sister and brother Ofelia and Avilio grew up in the family's home town of La Democracia, in Huehuetenango, orphaned when their parents were killed in the years of violence.
Their sister Elsira, however, was adopted more than 20 years ago by a family in Honduras. In San Pedro Sula, she studied to be a nurse and started a family, all without knowing where her siblings were.
The reunion was made possible when the Mutual Support Group helped reunite another of the family's children, Criserio, with brother Avilio.
When their picture was posted on Facebook, their missing sister Elsira spotted her brothers, and promptly contacted the Mutual Support Group for help.
"I felt so happy because I have found my sisters and brother," said the woman, now 35, who was four when she lost track of her siblings.
Of the family's seven children, four have been brought together while three are still missing: Victor, Estela and Roberta.
