Thirteen Grandmothers review: Why does it switch between 13 and thirteen? For a consistent flow thirteen needs to be spelled out for all mentions of the Thirteen Grandmothers. Some sources can use an update. Either the source is not good enough or needs more detail. Many Grandmothers have no information on themselves.

New source: http://www.grandmotherscouncil.org/our-mission The thirteen Grandmothers are on a mission to heal the earth with prayer and pass this good fortune onto the next 7 generations. They are concerned with the overall destruction of the earth and the indigenous way of life. They believe the teaching of their ancestors will help reach this goal. Using the land, medicines, language and ceremonial prayer they can pass on their teachings to the future generations.
