(brother) Jane Addison (née Campbell, later Pocklington; 1771 – 27 February 1851) was the first woman in the United Kingdom to petition a divorce (with the ability to remarry) against her husband through an act of Parliament and did so with success.
The family belongs to the Inverneil branch of the Clan Campbell and could trace their heritage to the back to the 16th century.
[2] Her father was a Member of Parliament who occupied the seat in 1776 in place of his brother Sir Archibald Campbell who was abroad fighting in the American Revolutionary War.
The affair was deemed to be incest as marriages between a man and his deceased wife's sister was voidable (later made illegal).
[2][1] Mrs. Addison attained a legal separation from a religious court on the basis of adultery with success and wanted a divorce.
[2] Testimonies from various individuals including waiters and servants indicated that Mr. Addison and Mrs. Jessie Campbell were indeed having an affair beyond doubt.
[1] Mrs. Addison was free to remarry and also attained custody of her children as her husband was deemed unfit to take care of their education.
