An autopsy on her remains proved inconclusive and the cause of her death will not be determined until the results of toxicology tests are complete in another week or two.
Geldof's funeral will be held the day after Easter at Mary Magdalene and St. Lawrence Church.
The church is where her father married her mother, Welsh TV host Paula Yates, in 1986, and where Geldof married her second husband, musician Tom Cohen, in 2012. The church is also the site of Yates' 2000 funeral. She died of a heroin overdose at the age of 41.
In addition to her father and husband, Geldof left behind two young sons and her sisters Fifi, Pixie and Tiger Lily.
