A U.S. Marine Corps veteran, the corporal was deployed to Afghanistan -- multiple times -- and Japan, his obituary says.
More than $3,600 had been raised as of Monday afternoon on a GoFundMe for Williams' family to assist with funeral expenses.
"If you knew Kenny, you were lucky," says the page, launched by Reggie Harrison.
"He had such a big heart and was willing to give the shirt off his back, even to a stranger.
"He was a Marine’s Marine, always willing to go above and beyond and did it with a smile."
Williams was predeceased by his mother, Joan Williams. He is survived by his father, Ken Williams, Sr.; sister Kellie Williams; and Dog Thor Williams of Elmwood Park.
Interment was at George Washington Memorial Park in Paramus.
