Is gil Scott heron Jill Scott's dad?

YES Sorry but your answer is incorrect. No he was not Jill's father. Gil Scott Heron's last name was Heron. Jill's father was Charles Scott of Philadelphia. He was a friend of mine and I just found out he died back in March of this year. Here is some of his obituary from the Philadelphia Tribune:

Charles Scott Jr. was a bricklayer.

Scott died Saturday, March 23, 2013. He was 65.

He was born July 13, 1947 to the late Sandra U. Scott and Charles Scott Sr. in Chocowinity, N.C. He was eldest of three siblings.

Scott was educated in the Philadelphia public school system and graduated from Edison High School. He served in the Army during the Vietnam War from May 26, 1967 to May 25, 1973. He is survived by his daughters, Jill Scott, Stacy Gongales, Charnita Scott and Asia Vinson-Scott; a sister, Vickie Scott-Weed; brother in-law, Charles Weed; aunt, Andre Whitfield of Washington, N.C.; four grandchildren; friend, Marvin Crawford, and other relatives and friends.
