No...They were long distant cousins and most likely that isn't even true.
And Jack the Ripper was an american named...
Francis Tumblety (c. 1833–1903) was a seemingly uneducated or self-educated Irish-American from Rochester, New York. He earned a small fortune posing as an "Indian Herb" doctor throughout the United States and Canada, and occasionally travelling across Europe as well. He was commonly perceived as a misogynist and was connected to the deaths of some of his patients; he was charged by the authorities in Canada, but skipped the country. He was also charged with supplying herbs to procure an illegal abortion. He gained a reputation for his eccentric, ostentatious clothes, which were frequently of a military nature. Tumblety was arrested on 6 May 1865 in St. Louis, Missouri and incarcerated in the Old Capitol Prison, Washington, D.C., for complicity in the Abraham Lincoln assassination, but was later released as having no involvement.
Tumblety was in England in 1888 and had visited the country on other occasions; during one such earlier trip he became closely acquainted with Victorian writer Hall Caine, with whom it was suggested he had an affair and from whom he tried to borrow money. He claimed to have treated many famous English patients, including Charles Dickens, for a variety of illnesses. He was arrested on 7 November 1888, on charges of "gross indecency", apparently for engaging in homosexuality, which was illegal at the time. Awaiting trial, he instead fled the country for France on 24 November 1888, and thence to the United States. Already notorious in the United States for his self-promotion and previous criminal charges, his arrest was reported in the New York Times as being connected to the Ripper murders. American newspaper reports that Scotland Yard tried to extradite him were not confirmed by the British press or the London police. The New York City Police, who had him under surveillance, said, "there is no proof of his complicity in the Whitechapel murders, and the crime for which he is under bond in London is not extraditable".
After the initial interest in Tumblety in 1888, he was mentioned as having been a Ripper suspect by former Detective Chief Inspector John George Littlechild of the Metropolitan Police Service in a letter to journalist and author George R. Sims, dated 23 September 1913. Tumblety died in 1903 of heart disease in St. Louis and is buried in Rochester, New York. In the episode of Mystery Quest featuring Jack the Ripper, Francis Tumblety fit the profile, being the most contemporary suspect.
He found out his wife was a prostitute, so he took out his anger on other prositutes.
He also had a hatred for women which caused his homosexuality.
And the murders stopped when he left england to return to the united states.
And the infamous "From Hell" letter matched his handwritting.
They had a documentary on him, proving it was him.
None of the evidence linked anyone but him.
