I believe The Henry Marshall Wallen you are looking for was my great grandfather. He was married twice one of his wifes was Lytha Guthie. Somewhere along the line of this large family, the older ones spelled their names WALDEN THE YOUNGER SPELLED WALLEN
Henry Marshall Wallen's son Evin (my grandfather) married mary ethel Turner Wallen. They had 5 sons one of which was my father, Windle Wallen who had 6 daughters and one son.
