Rhonda says, via Ancestry:

"David, My mother Gladys Cunningham was married to Dennis for a few months. I am NOT Dennis's daughter. My father is Harry Spain. Dennis married Helen, then Gladys, and then a third lady. I might have her name some where. I was born in 1953. I hope this helps. Rhonda Spain-Minchew.

"Dennis married Helen in 1941, Payette, Id. Gladys April 12, 1952, in Id. Divorced June 26, 1952 in Grant Co. Or. Margaret Nov. 1, 1953 Crook, Or."

Note: The DNA evidence indicates that Rhonda is indeed, genetically, the daughter of Dennis L. Martin, and Ancestry shows many shared connections with Martin/Rooney relatives.

It appears that, in addition to their earlier Idaho marriage record, Dennis and Lois also have a marriage record for 27 Jul 1942 in Clark, Washington.
