Twins Hiroshima Kindelan (girl) and Nagasaki Kindelan (boy) were born in Cuba in 1978. Several years later they moved to the U.S. and settled in the Miami area.
The names were chosen by their father. During the pregnancy, he thought of the twins as “booming” inside his wife “like two bombs.” Hence the names Hiroshima and Nagasaki.
