Powell and his family moved frequently across the mid-Southern US, with all the children except two being born in different locations in different states.〔("Alvah Leigh Powell" ), at ''Ancestry.com'', accessed 5/28/2013.〕 Some sources indicate that Powell was a minister during these years,〔''Free Wheeling Powell-Lever Engine'', by Menno Duerksen, Cars & Parts Magazine, March 1975, reprinted in Farm Collector, January/February 1997.

Powell divorced Ada in 1903 and remarried to Bertha M. Flowers in 1905. There were no children from the second marriage.
