Rosemarie "Rosin"

Rios

With heavy hearts, we announce the peaceful passing of Rosemarie Rios at the age of 83 on Monday, December 15, 2025, surrounded by her loving family in the comfort of her home. For the past four years, Rosemarie showed remarkable courage as she faced ongoing health challenges, always maintaining her warm spirit and love for those around her.
Born on September 26, 1942, in Naranjito, Puerto Rico, Rosemarie was one of eleven children born to Isabel Baez and Jesus Nieves. She received her early education in Puerto Rico before embarking on a new chapter of her life when she moved to Long Island, New York, in 1972. Eventually, she settled in Chelsea, where she would cherish over 46 years of community and connection.
Rosemarie was married to Faustino Atanacio, and though she faced the heartache of widowhood, her spirit remained unbreakable. A devoted mother to her five children, Rosemarie's love for her family knew no bounds. She was an integral member of St. Rose of Lima Parish in Chelsea, where her faith and dedication shone brightly.
Known for her love of dancing and her warm, welcoming nature, Rosemarie became a beloved figure in her neighborhood. She was often found sitting on her front door steps, a friendly ambassador to all who passed by, greeting friends and strangers alike with her genuine smile.
Rosemarie was predeceased by both her parents and seven siblings, but she leaves behind a legacy of love and strength. She is lovingly survived by her devoted son and caregiver, Jorge D. Atanacio, as well as her children Orlando Atanacio and Maria Medina in Puerto Rico, and Jose Rios and Ana I. Vega of Chelsea. Her family will also honor her memory with the love of 14 grandchildren, 10 great-grandchildren, and 18 great-great-grandchildren, along with her siblings Cheo, Juan, and Luz Nieves.
In celebration of a life beautifully lived, relatives and friends are warmly invited to attend visiting hours at Welsh Funeral Home, located at 718 Broadway, Chelsea, on Thursday, December 18th, from 6:00 PM to 8:00 PM. The funeral will take place at the funeral home on Friday, December 19th, at 9:00 AM, followed by a Funeral Mass at St. Rose Church, 600 Broadway, Chelsea, at 10:00 AM.
As we gather to honor Rosemarie's spirit and the profound impact she had on all of our lives, we find solace in the love and memories she leaves behind. May her soul find peace, and may we carry her love with us always.
