It is possible that your William Lafayette is the son of Alfred B. and Susan. Alfred the son of Spencer and Mariah Scroggins in Polk Co. Tn. 1840 and 1850. William and Mary are in Jasper Co. MO in 1910 - with Harold age 4 and Leonard age 1(perhaps her name was Jennie Mary or Mary Jennie = he, age 38 and she, age 23, if I copied it correctly). There is a William L. age 8 in 1880 on the Texas Co. MO Census as son of Alfred B. and Susan. Alfred was born in Rutherford Co. NC At least it is something to check.
