By 1930, W. P. is gone from the household, and Alice and the kids were in Big Gap, Wise County, TN.
I suspect that the Harrison Wallen is a brother, and that your W. P. is Willie Wallen, son of John Wallen, born 1854. and Elizabeth Fleenor.John Wallen was a son of William J. "Big Sandy" Wallen and Jane Banks.
If these are your Wallens, there is a lot of information available about them.
