Where can I find sources for Jewish land use/rent/ownership in the late 19th century in the Ukraine?  
Trying to locate the name of my gggrandfather possibly J. Laske  and his wife/wives and children from Gobnik/Hubnyk near Ladyzhin.  Hitting lots of brick walls.  I know he was in the forestry industry and well off before being murdered in a pogrom in 1905 (possibly by his employees).
