If the child is born within that society, the society would demand the child take the father's name in accordance with their rules.
However, If the mother departed the clan before giving birth to the child, she would be able to give the child a name in accordance with her own Moonkeeper traditions.
Likewise, if the father was in fact a Tia (maybe even a former nunh) who had left Sunseeker culture when he mated with the Moonkeeper female, the mother's culture would likely again apply.
Things would get far more interesting if the father was a Moonkeeper and the mother was a Sunseeker, so neither parent would have a naming convention to pass on.
