After meeting her husband, she moved to Rhode Island where she raised her three children in Cranston and supported her husband as he built his business. Effie was “Yiayia” to more than just her grandchildren and anyone who met her will never forget her formidable presence, loving heart and quick sense of humor.

She also leaves behind her siblings, Tina Tavlas Demopulos of North Providence, RI, Martha Tavlas Iazzetti of Naples, FL and George Tavlas of Athens, Greece, and her sister-in-law, Evelyn Rae of Warwick, RI in addition to many loving nieces and nephews.
