On Great Big Yam Potatoes, a collection of Mississippi field recordings culled from 1930s Library of Congress recordings, Charles Long and Sam Neal play a fiddle tune entitled "My Little Dony." Unfortunately, the liner notes do nothing to explain "Dony", but there are some words sung:

MY LITTLE DONY

Eyes just like a cherry
Cheeks just like a rose
How I love my Dony
God in Heaven knows

Fair you well my Dony
Fair you well, I say
Fair you well my Dony
Come another day

You can ride the old grey mare
I will ride the roan
When you go a-courtin'
Let my Dony alone

Preacher in the pulpit
Bible in his hand
Said he wouldn't preach no more
'Till he got another dram

Wish I had a band box
Put my Dony in
Take her out and kiss her
Put her back again
