Eva and Ava Brown Williams died April 4, when flames erupted at their Margate Road home, according to a GoFundMe launched by their grandmother, Christina Brown.
The girls' mom escaped by jumping out of a window, and suffered injuries — as did two firefighters at the scene.
Christina Brown tells CBS News that she had been working on arrangements for her son, Denzel Brown, at the time of the fire. He was killed on March 27 in Strawberry Mansion, according to Fox29.
More than $8,600 had been raised in honor of the Brown-Williams twins as of Sunday, April 9. Click here to donate.
