Help me find my aunt Esperanza after 20 years apart

My aunt Esperanza and I were separated in 2006 during what was supposed to be a routine stop near New York. That was the last time I saw them. We had been living peacefully for years when everything changed overnight. Esperanza was 54 years old at the time. The separation happened because of being picked up by immigration agents in New York. What I miss most is staying up late telling stories by flashlight when the power went out. The messages suddenly stopped in 2015. Every lead has gone cold. Esperanza would be around 74 years old now. Last I saw them, they were average height, lean build, with curly black hair. Every time I see someone who looks like them on the street, my heart stops for a moment. If anyone has any information about Esperanza, please reach out. Even knowing they are alive would mean everything.
