ДНК S09E94 - Выпуск 1285. Заменила мать чужой сестре?

A resident of Pskov was horrified when she saw the conditions in which her paternal sister was growing up. She took the girl in, got married, and now she's raising her like her own daughter. But she doubts whether they are related by blood, because there were various rumors about the girl's mother. Is a woman really giving herself all to a girl who is not her own blood? And what would she do if their relationship wasn't confirmed?
