The foundation announcement followed a prayer vigil Wednesday night in Chicago.
"Jennifer sang her first song in this church – she said her first prayer in this church," her cousin Shari Nichols Witt said of the Pleasant Gift Missionary Baptist Church. Witt also spoke fondly of the actress-singer's slain nephew, saying 7-year-old Julian King "seemed like he was ahead of his time."
The Rev. Jesse Jackson, who spoke at the vigil, told PEOPLE that Hudson, 27, and her family "are overwhelmed by the suddenness and the unexpectedness of it all. This family knows triumph, and they also know tragedy."
As the community grieved the loss of the Dreamgirls
star's relatives, the 27-year-old parolee considered a suspect in their shooting deaths, William Balfour, remained in police custody Thursday.
Balfour – the estranged husband of Hudson's sister Julia – was being held on an alleged parole violation
