In the 1920 Sullivan Co. Tennessee Census there is Lowery Morelock age 53 with wife Annie and children:
Carp age 24 Bradley age 11 Bynun age 19 Moody age 18 Virgro age 16
I believe Lowery is probably William Lowery Morelock and wife Anna Light. William Lowery the son of Samuel Morelock and Priscilla Grimsley. In the 1880 Hawkins Co. Tennessee Census we have Samuel Morelock age 53 and wife Chrisis age 60, (I believe this is Priscillia) with Children; George W. age 24 Marrion age 24 Ruben age 21 William L. age 20 John (a grandson of Samuel) age 7
This Samuel is the son of Samuel Morelock and Elizabeth Stacy (This is also my ancestor). This Samuel is the son of George Morelock and Elizabeth Bachman.

that this family primarily lived in Kingsport but were originally from Hawkins County. Walter Lowery (Bud) Morelock lives at Beech Creek and would be one of your close cousins.
