When I got home, I dragged the box onto my kitchen table.

Birth certificates. Tax forms. Medical records. Old letters. I dug until my hands shook.
At the bottom was a thin manila folder.
Inside: an adoption document.
Female infant. No name. Year: five years before I was born.
Birth mother: my mother.
My knees almost gave out.
Behind the folder was a smaller folded note, written in my mother’s handwriting.
I cried until my chest hurt.
It read:
I was young. Unmarried. My parents said I had brought shame. They told me I had no choice. I was not allowed to hold her. I saw her from across the room. They told me to forget. To marry. To have other children and never speak of this again. But I cannot forget. I will remember my first daughter for as long as I live, even if no one else ever knows.
I cried for the girl my mother had been. For the baby she was forced to give away. For Ella. For the daughter she kept—me—who grew up in the dark.
When I could see again, I took photos of the adoption record and the note and sent them to Margaret.
She called right away. “I saw,” she said, voice shaking. “Is that… real?”
“It’s real,” I said. “Looks like my mother was your mother too.”
We did a DNA test to be sure.
Silence stretched between us.
“I always thought I was nobody’s,” she whispered. “Or nobody who wanted me. Now I find out I was… hers.”
“Ours,” I said. “You’re my sister.”
The DNA test confirmed what we already knew: full siblings.
