Document 4: Jack London: Jack London's mother, Flora Wellman, was the fifth and youngest child of Pennsylvania Canal builder Marshall Wellman and his first wife, Eleanor Garrett Jones.  Marshall Wellman was descended from Thomas Wellman, an early Puritan settler in the Massachusetts Bay Colony. Flora left Ohio and moved to the Pacific coast when her father remarried after her mother died. In San Francisco, Flora worked as a music teacher and spiritualist, claiming to channel the spirit of a Sauk chief, Black Hawk.Biographer Clarice Stasz and others believe London's father was astrologer William Chaney. Flora Wellman was living with Chaney in San Francisco when she became pregnant. Whether Wellman and Chaney were legally married is unknown. Most San Francisco civil records were destroyed by the extensive fires that followed the 1906 earthquake; nobody knows what name appeared on her son's birth certificate. Stasz notes that in his memoirs, Chaney refers to London's mother Flora Wellman as having been his "wife"; he also cites an advertisement in which Flora called herself "Florence Wellman Chaney".According to Flora Wellman's account, as recorded in the San Francisco Chronicle of June 4, 1875, Chaney demanded that she have an abortion. When she refused, he disclaimed responsibility for the child. In desperation, she shot herself. She was not seriously wounded, but she was temporarily deranged. After giving birth, Flora turned the baby over for care to Virginia Prentiss, an African-American woman and former slave. She was a major maternal figure throughout London's life. Late in 1876, Flora Wellman married John London, a partially disabled Civil War veteran, and brought her baby John, later known as Jack, to live with the newly married couple. The family moved around the San Francisco Bay Area before settling in Oakland, where London completed public grade school.

Document 7: San Francisco: San Francisco was founded on June 29, 1776, when colonists from Spain established Presidio of San Francisco at the Golden Gate and Mission San Francisco de Asís a few miles away, all named for St. Francis of Assisi. The California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city - county in 1856. After three - quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama - Pacific International Exposition nine years later. In World War II, San Francisco was a major port of embarkation for service members shipping out to the Pacific Theater. It then became the birthplace of the United Nations in 1945. After the war, the confluence of returning servicemen, massive immigration, liberalizing attitudes, along with the rise of the ``hippie ''counterculture, the Sexual Revolution, the Peace Movement growing from opposition to United States involvement in the Vietnam War, and other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States. Politically, the city votes strongly along liberal Democratic Party lines.

Document 15: Frisco Jones and Felicia Cummings: Felicia Cummings arrived in Port Charles in 1984, dressed as a boy and intent on getting back an Aztec heirloom, in the form of a ring that Frisco Jones had purchased. Felicia claimed the ring as hers and had every intention of getting her property back. While attempting to get her ring back, Felicia quickly attracted Frisco and the two started to fall in love. But Felicia was engaged to the treacherous Peter Harrell (Judson Scott) and therefore could n't take her relationship with Frisco any further, at the time. After the ring dilemma was settled, Frisco and Felicia traveled to Mexico with Robert Scorpio (Tristan Rogers) and his wife Holly Sutton (Emma Samms) in search of a treasure. Along the way, Felicia also attracted the attention of Sean Donely (John Reilly), but after she turned him down, he became more of a father figure to her and nicknamed her ``princess. ''A year later, Felicia became entangled in another adventure and this one took place in the Asian Quarter. While there, she befriended Jade Soong (Tia Carrere), the granddaughter of the evil villain Mr. Wu, and helped Robert and Anna Devane (Finola Hughes), with their young daughter Robin Scorpio (Kimberly McCullough). She also helped Frisco and Sean stop Mr. Wu's reign of terror and bring him down. Before and during the Asian Quarter adventure, Frisco and Felicia progressed in their relationship and began to date more steadily. Together they moved into a small studio apartment at Bobbie Spencer's (Jacklyn Zeman) Brownstone. After coming to terms with his chosen occupation with the World Security Bureau, Felicia marries Frisco in 1986. They married at the Brownstone and since Frisco was in the police academy and could not travel away, Sean gave them a private honeymoon in his penthouse.
