There was a Jacoba Gallegos from La Placita or El Prado. Taos County, NM married to Rafael Garcia on 13 Jan 1886. She died on 23 April 1886. Her parents were Rafael Gallegos and Maria Guadalupe Medina. This records from Our Lady of Guadalupe Catholic Church in Taos. She did have a child, Vidal Montoya, out of wedlock. His father was Martin Montoya.
I hope this helps.
