My ancestors used to own Laparovichi manor, before the Treaty of Riga. Not sure if you know about a useful source of pre-WWII maps. e. g. for Laparovichi http://www.wwii-photos-maps.com/prewarmapsn35-1-50000/slides/N-35-67-D. html Not 19th century it's true, but more accurate than post-war maps. Cześć.
