Thank you stefan and Micheal for your help. Some explanation:
Moskalewszczyzna was the very small village where my Grand-Father and
my Uncle were born, as well as some other members of my Father's
family. I know for sure it was in Lepel powiat beacuse I have some
writen documents about the history of the family and I found this
Jelno you found, Micheal, can not be the one I was looking for. My
grand-father build there a mill on the river Jelenka. It has to be in
the Wilenszczyzna, in the Hermanowicze, Braslaw, Miory, Glebokie
region because this is where my family was located during the period
between the wars.
Why I'm asking these questions? I'm writng a book about my Father and
I want to have as much information as possible. My Father was 24
years old when Hitler and Stalin attacked Poland, he
was "zmobilizowany do" 13 Wilenski Pulk Kawalerii, in 1939 was first
time disarmed by the Soviets, then "internowany" by Lithouanians,
then worked legally and illegaly in Wilno, in July 1944 second time
disarmed by the Soviets and finally was forced ("repatriacja") to
leave everything and move to Poland. He was an architect, lived in
Poland, France and Canada and was very unusual, highly talented,
incredibly honest person.
I spent a week this summer in Bialorus and Wilno trying to find
something from the past and had a very emotional encounters with
people and places.
