Yes, Jameson was orphaned during the Rat Plague, and was adopted afterwards - hence the fact that Emily and Jameson could 'grow up together' and Callista (who was still alive after D1 until her later disappearance could teach him as well as Emily).

Since the adoption took place the Rat Plague, it is feasible for the Callista's statement to be true about Geoff and her being the only Curnows at the time she wrote the letter and the adoption to take place shortly thereafter. However, omitting the adoption itself in the novel and other side media was admittedly an oversight.
