In "The Wheel of Time Companion" it is hinted that the mother and all the sisters of Egwene can learn to channel.
She braided her hair at sixteen. According to Egwene, she has a tendency to treat her "like a baby."
Berowyn married in the year 989 NE a man of the Lewin family, and had a son. However, her husband and son both died of Breakbone fever in 990 NE.
Berowyn could not run her farm alone, so she sold it to her in-law and returned to the al'Vere home also because she never got on with her husband's mother.
Berowyn later married again with an outlander, one of the refugees who entered the Two Rivers recently.
