I am searching for information on the family of JOHN B. KNIGHT. He was born 17 Feb 1799 in Lancaster, Lancaster County, South Carolina. He died 01 May 1875 in Brown County Illinois. He married Martha Patsey McKinney Knight (her second marriage) 07 Apr 1847 in Brown County, Illinois. Two of their children were Susanna Knight born 07 Apr 1847 in Brown County, Illinois , and Ellen Eliza Knight born 16 Oct 1851 in Brown County Illinois.. Any information on this family will be greatly appreciated. Wendell Haack
