When Tim Farrell helped found the eponymous Terry Fund in the months after Sept. 11, 2001, to memorialize his brother, an FDNY firefighter killed in the attacks, the charity gave small $500 scholarships, said their sibling and the fund’s co-founder, Brian Farrell. In the 18 years since, the fund, named to honor Terry Farrell, who died while serving with Rescue 4, has expanded across the country, with 17 chapters from New York to California, including Colorado, Delaware, Florida, Georgia, Ohio, Pennsylvania and Nevada.
