This is from the Newcastle Chronicle of August 1766. When researching wife selling it seems many people believed that if a man went away for 7 years his wife was free to remarry. This may be where the notion comes from but I’ve never come across it in England. there is no mention of what happened to his wives.
Yesterday came on before the High-Court of Judiciary the trial of Alexander Ogilvy (brother of the late unfortunate Tho. Ogilvy of Eastmiln, and Lieut Patrick Ogilvy) indicted for the crime of bigamy, or marrying a second wife, the first being still alive; when he gave in a petition craving banishment furth of Scotland, to which his Majesty’s advocate having consented, he was accordingly banished Scotland for 7 years, with the usual certifications.
