My great-great grandfather was Melety (Meletius) Dutkevich, born approximately 1840-1850 in Russia (Poland). He was an administrator and professor of botany at the University of Warsaw, which was part of Russia at the time he was there. I believe that he originally taught at the University of Vienna.
He had 11 children, including my great-grandmother Olga (1875-1964) and her brother Meletius Peter (1871-1939). He came to the United States in 1889 and travelled the world as a photographer. She married, moved to the United States in 1924 and settled in New York.
I may also have made a connection to another of the 11 children. My grandparents' immigration documents list an Alexander Dutkevich as their contact in Russia.
There is an Alexander M. Dutkevich and his son George Alexandrovich on the G-to-G geologists website. They were apparently executed by the Nazis in 1937 for supposed subversive activity. The dates and city of birth (Yekaterinaslav/Dnipropetrovsk) are correct, so I am going to go out on a bit of a limb and assume that the M stands for Meletovich.
