The many differences in the age and marriage partner recorded on different sites proves confusing.
Her birth is usually quoted as 1146 but 1135 is also, but rarely, mentioned.
Marriage is usually quoted as Eynion de Tilston but Ralph de Malpas is also mentioned.
First born of marriage to de Tilston is quoted as 1154 and first born of marriage to de Malpas quoted as 1150.
Obviously these dates cannot be correct. Any information on dates and marriage partners would be most welcome.
