Well, well

From Pierre; Or, The Ambiguities (1852):

"Well, well, well," cried Pierre rapidly and impetuously; "we both knew that before."
"Well, well, well, Pierre," retorted his mother, mockingly.
"It is not well, well, well; but ill, ill, ill, to torture me so, mother; go on, do!"

Dearest Lucy!—well, well;—'twill be a pretty time we'll have this evening; there's the book of Flemish prints—that first we must look over....

"Well, well; go on, go on, aunt; you can't think how interested I am," said little Pierre,

Well, well, I never thought to cast them back into the sordid circulations whence they came. 

"Well, well, wonders is all the go. I thought I had done with wondering when I passed fifty; but I keep wondering still.... Well, well, well, well, well; of all colics, save me from the melloncholics; green melons is the greenest thing!"

"Oh! is that you, sir? well, well, then;" and the man set down the easel.

"Well, well, Isabel," stammeringly replied Pierre; while a mysterious color suffused itself over his whole face, neck, and brow; and involuntarily he started a little back from her self-proffering form.

The locution Well, well occurs 9x in Moby-Dick, for example:

Well, well, what’s signed, is signed; and what’s to be, will be; and then again, perhaps it won’t be, after all.

C.—"Well, well,—I wrote what pleased myself; and,—another object I have, which I did not mention: with scarce a book to read, if one did not write, I fancy the beef and pork and beans would in time form a coating round his brain,—turn it all perhaps to thick and solid skull! How is it with you, Frank? Does yours retain a slight softness?"
