The 54-year-old actor has three siblings, Lee Ann Mapother DeVette, Marian Mapother Henry, and Cass Mapother — and they basically all look like Tom's twin!
Let's take a step back in time to learn a bit more about Tom's family, shall we? The future-actor was born Thomas Cruise Mapother IV on July 3, 1962, in Syracuse, NY. His parents, Mary Lee Mapother South and Thomas Cruise Mapother III, worked as a special education teacher and an electrical engineer, respectively.
Mary Lee and Thomas welcomed their first child, daughter Lee Ann, in 1959. Two years later, the couple had daughter Marian. Tom's younger sister, Cass, was later born around 1964.

Tom and his three sisters unfortunately grew up in near-poverty and their father was abusive. The siblings — who were raised Catholic — later moved to Canada before their parents split in the mid-1970s.
In a 2016 interview, Tom's first-ever girlfriend opened up about his close relationship with his siblings. "I think he grew up too fast but he was very close with his three sisters. One time he said he's so close with them they taught him how to kiss," she told the [Daily Mail](http://www.dailymail.co.uk/tvshowbiz/article-3453270/Portrait-young-Tom-Cruise-love-fame-money-Scientology.html?ito=social-twitterdailymailceleb)_.

A year later, however, Lee Ann was replaced by veteran celebrity rep Paul Bloch. Starting in 2005, Tom's sister instead worked for the actor's production company.
Earlier this year, the Mapother siblings' mother, Mary Lee, sadly died peacefully in her sleep at age 80 in February 2017. Tom and his three sisters all subsequently attended a memorial service for Mary Lee at her local Church of Scientology.
