@Foofie,
In Russia, and especially in and around Brest, many Jews lost there homes due to local major blazes (like in 1887, 1895 and 1901).
In the German Jewih press you can find dozens of notices for and reports about collections to help the Russian Jews.
Between 1881 and 1914 more than 700,000 Russian Jews emigrated to the USA via Hamburg.
In 1884, Hamburg Jews founded the "Hilfeverein für mittellose russische Juden"(a charity for stranded and fundless Russian Jews). (More than 10,000 had to get help already in 1881). - Jews called Hamburg "Vater der Auswanderer" (father of emigrants).
