Okay, here's something I've been toying with. Not sure if this should be canon.
The Summers Family
Scott Summers: Third cousin to Duncan Summers, the original Raven, Scott was a crusader for Metahuman rights in the 60's and 70's under the name Cyclops. , along with his then girlfriend, Jean Grey, his younger brother, and a number of younger meta-humans who attached themselves to his cause.
Scott retired to his childhood home of Anchorage, Alaska after Jean disappeared in the early 90's. He still lectures on metahuman rights, and has been known to teach for a semester or two at some of the meta-human schools, particularly Claremont and Charles Xavier's School for Gifted Youngsters.
Alex Summers: Scott's younger brother. While he had a deep rivalry with his older brother (mostly because Scott had or did everything he ever wanted, only better), Alex has gotten over that and moved on with his life. Also retired, he teaches Geology at Claremont.
Jean Grey/Summers: Scott's one time girlfriend and now vanished wife. Jean was possessed by a cosmic force of Rebirth known as the Phoenix a number of times over the course of several decades, but, shortly after the birth of their second child, she was possessed for the final time, leaving for deep space, and has not been seen on Earth since.
Nathan Summers: Scott and Jeans's first child, Nathan inherented his mothers talent for Telepahty and Telekinesis. Nathan is currently estranged from his father over what he sees as abandoning his responsibility to his infant daughter after Jean's disappearance.
Nathan took a number of years off in the 90's to raise his younger Sister, as well as his own daughter, Hope. He currently does work of AEGIS when needed.
Rachel Summers: Like her older brother, Rachel inherited her mothers abilities. Unlike her brother, she seems to share some of her mothers connection to the Phoenix, her powers occasionally manifesting as a fiery bird and operating far in excess of her normal levels. Currently in her late teen, Rachel has started doing intern work for SWORD, hoping to hear news of the mother she never knew.
Hope Summers: Nathan won't say who Hope's mother is. Some have speculated she isn't his daughter at all, but is a manifestation of the Phoenix itself, or just a child he found. While there is resemblance to Jean, her powers are the ability to mimic the abilities of any metahuman in her area, which are completely dissimilar to any of her relatives abilities. Hope is currently in her senior year at Charles Xavier's School for gifted youngsters.
Christopher Summers: When Scott was eight, he saw his mother and father kidnapped by alien slavers. While his wife died to their depredations, Christopher eventually led a rebellion, taking revenge for her and leading the escaped slaves to become the space pirates known as the Starjammers. He would, decades later, reunite with his sons, though he rarely returns to Earth any more. Still alive and in good health from alien medical technology, Nathan has retired from the pirate life, and now searches for a tropical planet to retire to.
Katherine Summers: Christopher's half human daughter with his mephistoid lover, Hepzibah. Kate appears as a teenage human with some feline features (Ears on the top of her head, a tail, some fur, feline eyes, whiskers). She has recently taken command of the Starjammers from her father, although his old friend C'hod tries to temper her youthful enthusiasm with age and wisdom.
