There are a bunch of "dark Anastasias" that I don't remember to see here. From the Russian claimant list at Wikipedia:
1) Josephine Fedele: younger sister Konchetty Fedele - "Olga Nikolaevna" -I've mentioned her at the Olga's claimants thread-. On the assurances of her children escaped with his brother and sister because of a secret treaty between Germany and Soviet Russia.
2) Lyubka Tersieva: as a citizen of Bulgaria. Её внучка продолжает отстаивать права своей «царственной бабушки». Her granddaughter, continues to defend the rights of his "regal grandmother."
3) Peregudova Alexander: died in the Volgograd region in 1982. According to this version, all the Romanovs survived because a train driver took them to Siberia, he was able to substitute for some seven doubles. The fate of the remaining survivors remained unknown.
4) Anastasia of Moscow: real name unknown. According to her, "State Secretary" Pakhomenko Leonid Smirnov, who filed an application to the Supreme Court of Russia , she was taken to Moscow in 1918 , along with polka Anna Tshinkovskoy (apparently - the distortion of the name Shantskovska), to play its role in Europe and thus gain access to the Tsar's millions. The real princess, according to Parkhomenko, were sent to Siberia, and her four children poisoned for orders of Stalin. The fifth son he was going to marry his daughter, but allegedly later changed his mind. In the 1980s, the Grand Duchess moved to Moscow. With his "new name" Alexander Parkhomenko -I suppose the son of this "Anastasia"- declined. Story has not been further progress.
-Sorry for the bad quality of the translation, that makes the story unclear... I've tried to correct it but with not much success-
5) Alexandra Spiridovna Karpenko: resident of Omsk. She died in 1976 . A kind of monarchist-minded conspirators stole Anastasia, and they tried to take her away on a cart. Further in her own words looked like this: "I was carried in a cart, and when the riders have to catch up, I jumped out in a bog. And when all was quiet, I got out, and we again went on ... ". Apparently she escaped at 1920. She was adopted by a resident of Primorye, Spyridon Miroshnichenko. Her daughter named Anastasia contacted the writer Vladimir -Kashitsem (?, translation unclear)-, and told the "true story" of his mother.
6) Elena Kharkin - appeared in 1943. She was reluctant to talk about her past, however, because of the "apparent similarity" the locals took her by Anastasia Nikolaevna, who survived thanks to the substitution. Date of death unknown.
7) Anastasia Yakovlevna Karetnikova - also on the assurances of his son, along with Alexei Nikolaevich was injured during the shooting and then kidnapped by some unnamed monarchists. Rescued children transported to the Urals to the Ataman Dutov. Alexei died soon, Anastasia was too weak to go to Siberia after the retreating White Army,then she turned to Ksenia Karetnikov, the wife of the commander of the Reds, Budyonny (original Семена Будённого), and she remained with the family Karetnikov. Later she married Nikolai Ionov and gave birth to two children. She was killed in August 1936 , and, as her son says, the crime was concealed by the authorities and declared a suicide.
Her son: Anatoly Ionov wanted find solacefor her mother in the last royal tomb, and he was officially recognized as "the emperor in exile." He tried to write to President Putin, addressed to the newspapers, but his claims fell on deaf ears.
