Hi,
At this link,
http://www.rootsweb.ancestry.com/~arconway/ccmarrbkxbride.ht..., I found a marriage listed for a Walter Ply, age 21 and Eva George, age 17 dated April 9, 1922 in Conway County, Arkansas. This means Walter was born about 1901. Could he be a sibling of your Vida?
I am researching some Arkansas Ply family lines descended from Jacob and Rebecca (Adams) Ply. Hope the info is helpful.
