"Soldier, soldier, marry me" supposedly came from England in colonial times (acc. to Contemplator), but there is nothing in the Bodleian. Ozark Folksongs by Vance Randolph, like the North Carolina Collection, has versions. Can't find the Hobart Smith recording. What album?
The request is two years old and "Roberto" may no longer be interested.- did Smith record it?

The first verse of Randolph's version A has these first lines (giving the soldier quite an incentive):

Soldier, soldier, marry me,
And have a house an' home.

In another version in Randolph, The singer asks for a man named Deitcher to marry her.

Philippa and Guest, do you have any history on this song? The source may be Irish rather than English.
Newell, 1883, Games and Songs of American Children, printed the song. English versions were noted in the Journal of the Folk-Song Society, 1914, (Randolph) but I don't have any texts or dates.
