Feodor (or "Friedrich") Beinroth in former Russia (today Ukraine)
I am looking for Feodor Christianowitsch Beinroth (or Friedrich Beinroth) who lived in Trostyanets, Gouvernement Kharkov/Russia, today Sumskaya Oblast/Ukraine around 1905. Probably he was living and working with the Koenig family: Leopold Koenig (+1903) and his sons Friedrich Koenig (+1908) and Julius Koenig (+1927). He is probably a distant relative of the Koenig family.
