Here's a sea chantey that mentions Betsy Baker -- and rhymes her with "Quaker." Coincidence? Lyrics copied from http://www.acronet.net/~robokopp/shanty/cheerily.htm
I have put the refrain in italics.

CHEERILY MAN

O Nancy Dawson, Hio! Cheer'ly man.
She's got a notion, Hio-o! Cheer'ly man.
For our old bo'sun, Hio! Cheer'ly man, O!
Hauley, Hio-o! Cheer'ly man.

O Betsy Baker, Hio! Cheer'ly man.
Lived in Long Acre, Hio-o! Cheer'ly man.
Married a Quaker, Hio! Cheer'ly man, O!
Hauley, Hio-o! Cheer'ly man.

[Similarly:]
O Sally Rackett, Hio!
Pawned my best jacket, Hio-o!
And kept the ticket, Hio!

O the ladies of town, Hio!
All soft as down, Hio-o!
In their best gown, Hio!

O Polly Hawkins, Hio!
With her white stocking, Hio-o!
Beats all at talking, Hio!

O Kitty Carson, Hio!
Jilted the parson, Hio-o!
Married a mason, Hio!

O haughty cocks, Hio!
O split the blocks, Hio-o!
O stretch her luff, Hio!
