I can tell you that appeal to the state SC is possible, but unlikely in states that have an intermediate appellate court. And when possible, it is a determination of law, not facts, that the SC decides. The judge's decision was based on applying the law to the facts as he saw them. It is in the discretion of a judge to do so, needless to say. You could possibley petition in GA for jurisdictional change to a court in that state, your father being a member of the bar should provide help in the process. I don't think it's likely to turn out favorably, however. Full faith and credit comes into the picture: one state's legal decisions are given standing in all states.
All states have a mandatory one level above appeal route. Beyond that, unless of compelling interest to the SC--constitutional question or egregious error by the lower court, review is unlikely--especially in a matter of Family Law. Sounds like you're getting the shaft and wish I could offer more suggestions outside of get an attorney from out of town that isn't painted the same color as the other participants. Even in gun country, a lot of judges are liberal ******** based on where they went to Law School. Good luck.
