"She was 79 years old and passed away peacefully surrounded by family after enduring a long illness. We ask that our family's privacy be respected as we grieve our loss." While Aniston didn't share details of her mother's illness, according to reports, Dow, who was also an actress, suffered a series of strokes and lost the ability to speak and walk prior to her death.

The two reconciled after Aniston and Brad Pitt divorced in 2005.
