Ligota Wielka, just outside of Olesnica
As i suspected former Germany - plenty of history since 1945 but nothing before i expect. I'm in the same situation, i think German archives would be the best place to look, its difficult getting anything from Poland. I would suggest finding the German name for your town and then hopefully the name of the owners during that time, good line of investigation to get the ball rolling.
A couple of years ago we had a German family show up on our doorstep, as it turned out the ladies Grandfather owned our house and her father briefly lived here. I also have a friend in a similar situation who has traveled to Austria to meet the former owner of his mansion. He managed to access pics from the early 1900's and quite a few stories.
