Soccer star, homecoming queen and promising student Ashley (22) had dual Irish-American citizenship.
Ashley is a cousin of Olivia Burke, who also died in the tragedy.
Her parents, both originally from Ireland, live in Rohnert Park, California. Her father, George, said that it was the "worst day of his life."
"Ashley was loved by her peers. She was definitely a leader," said vice principal Josh Wilson, of Rancho Cotate High School, where Ashley graduated in 2011.
