Harris

My Harris line has been the hardest for me.My grandfather was William Arthur Harris born Apr 16,1884 Warren Co Ky-died Feb 22,1945 Lewis Co Tn.Married Lillie Mae Churchwell Nov 10,1916 Lewis Co Tn.Parents were Thomas B Harris and ML Litefoot/Lightfoot.I have found the records I need for William with exception to the 1930 census.William was not in the 1930 census for my grandmother but there wasn't a divorce.And it does state that she was still married.So where was Will??.......Thomas B Harris born Jan 10,1864 Allen Co Ky-died Feb 10,1948 Allen Co Ky,buried at Marthas Chapel Cemetery Allen Co Ky.Married ML Litefoot 1883 in Sumner Co Tn,later married Saphronie "Fronie" Jane Moody,Stamps,Bailey.The 1910 census has them married for 1 year.Charles Herschel Harris',brother of Will, death record has Tom Harris as father and Mary Lightfoot as mother.Emma Harris' (sister of Will) marriage bond to Albert Huffiness in 1907 has father as Tom Harris and Malinda Lightfoot as mother.So mostly likely the mother was Mary Malinda Lightfoot(or vice versa).Thomas Harris' death cert has Henrietta Dowell as his mother but father is unknown.If I could find out what the "B" in Thomas B was for ,maybe I could search under that.....Any help with this is greatly appreciated
