Swank Ueland questions...please help

Hello. My name is John Alan Ueland (from Philadelphia PA). My father is Rodger Alan Ueland (from PA). His father is Robert Ueland (originally Robert "Bobby" Swank but adopted by Elsa Ueland in the early 1900's). His true father was Phillip Swank (who were his parents?) & mother was Blanche Swank. Blanch was a Cherokee (100%?) and adopted by an Amish family named Albrecht? What was Blanche's real last name and her family history?
Now my mother is Kathleen Ann(e?) Berger (maiden name) Ueland. Born 9-15-1945 in Pennsylvania as well. Her father was John Alan Berger and his wife was either Emma or Elizabeth (Griffith maiden name) Berger. They lived in Bucks County outside of Philadelphia. John worked at the navy yards. E Berger was murdered by her own brother. Does anyone have info on this? It was 1964-1968. John Berger SR died just months later of a stroke. The house and land were taken by the banks. Also, Kathy Berger was actually the daughter to John Berger JR (who she thought was her brother) and her "parents" turned out to be her grandparents!
ANY information on these people or events would be great!
