Marina married an attorney Richard Schweitzer. They both championed Anna Anderson´s case after Gleb passed away and were much confused and unhappy when DNA testing proved she was not Anastasia. They were bent on finding a "mistake" in the testing, and Marina stated her belief that somebody wanted something "covered up" and that it is linked to Queen Elizabeth II.....
According to Wikipedia Marina helped to identify the remains of Dr. Botkin when they were found: His daughter Marina Botkina Schweitzer's DNA was later used to help identify the remains of her grandfather, Yevgeny Botkin, after they were exhumed along with other Romanovs in 1991 from a mass grave discovered in Ganina Yama near Yekaterinburg. Schweitzer's DNA was compared against the DNA of her maternal half-sister Kira, who also gave a blood sample, to help scientists isolate the DNA Schweitzer shared in common with her grandfather. This enabled scientists to create a "Botkin DNA profile" and use it to positively identify Dr. Botkin. Scientists in the early 1990s were unable to identify Dr. Botkin using mitochondrial DNA, or DNA that is passed down from mother to child, as they used it to identify the Romanovs. Schweitzer was descended from Dr. Botkin in the paternal line and didn't share mitochondrial DNA with her father and grandfather.
