Here's a song from The Library of Congress American Memory Collection:

OH! ROCK DAT CRADLE, SUSIE.
Words, James B. Marsh. Music, W. T. Keefer.
New York: Lieder, William J. A., 1883.

1. I love dat yella wife of mine.
Of all de gals, she takes de shine.
I really think her quite divine,
My honey and my joy.
I tells you suffen, boys, tonight,
And show you such a purty sight.
'Tis mammy's joy and dad's delight.
We's got a baby boy.

CHORUS: Oh! Rock dat cradle, Susie.
Rock dat cradle, Susie.
Rock dat cradle, Susie.
See you keep de chile from harm.
Oh! Rock dat cradle, Susie.
Rock dat cradle, Susie.
Rock dat cradle, Susie.
Mind you keep de baby warm.

2. I lub dat little baby dear.
His youthful voice is loud and clear.
He's got a mouth from ear to ear.
His eyes am mighty fine.
I think he am de smartest youth
That you can find in all de south.
He puts his fist right in his mouth,
Dat baby boy of mine.

3. To see him wink his little eye,
And jump, and crow, and laugh, and cry,
And wave his little hand bye-bye,
Dat chile am 'most divine;
And when he cries, I feel so bad;
And when he laughs, I'se mighty glad.
He's got a nose just like his dad,
Dat baby boy of mine.
