I didn't specify some of it, for which I apologize. The father's brother being Jeilla's father just seemed to make sense. It might even have led to Jeilla and her mother living with Enric and family, although that seems a bit much.
As for Enric's burial of his brother, it could be an elven thing. Rather than interring their dead they give them to the river. Otherwise it's just the family's connection to the river, and it seemed like a fitting way to say goodbye to his brother.
