Grune is listed in her marriage record to Khaim as the daughter of Preide. The Preide referenced above would've been in his early 50s, which is fine biologically (and may hint at an explanation for why she married someone twice her age). However., Khaia is not mentioned in that record, and she would've been 50 when Grune was born, so I have to think that Preide remarried and then had at least one child with his second wife.
