Any help on the location and dates for the birth and death of my Great Grandfather Konstantin Sidorenko would be greatly appreciated.
In the parish records where his wife and children changed their last name from Sidorenko to Siirdmaa, there is a note about Sept. 1847...which is a few years off Konstantin's estimated birth date. All I know is that he was Russian, a great chemist, chello player and that he married my Great Grandmother Martha Emilie Ernestine Jürjew (Jurjew) who was born January 26, 1880 Reval (Tallinn), Harjumaa.
My grandfather, Oleg Sidorenko aka Olev Siirdmaa was born on April 6, 1918 in Ekaterinodar., Krasnodar (/ˌkrɑːsnəˈdɑːr, -noʊ-/;[15] Russian: Краснода́р, IPA: [krəsnɐˈdar]), formerly Yekaterinodar (until 1920)
