41. Jewish Boys
My father is the youngest of 13 kids. But actually, my grandparents only had 9 kids. Grandpa ran a farm and had a truck to deliver the produce from his and the surrounding farms. During WW2 he drove to Amsterdam to deliver food and secretly brought back Jewish boys. He hid them on his farm pretending they were his kids.
Partially very nice of him, but he also just needed extra hands to work. After the war, most of the boys went home to family members, but 4 of them had no remaining family. He officially adopted those 4 boys and just went on as if they had always been part of the family.
