Until I looked further, I felt strongly that "the dear" is a euphemism
for "the devil," just as Marius stated.
For one thing, "the devil" need euphemizing. "The Dear Lord" never did.
There is even a superstition that even mentioning the devil would cause
him to appear ("speak of the devil") so all the more reason to
substitute a word!
"The devil knows..." is a reasonably common expression in the 19th
century. Twice as many Google Books hits then as for "the dear knows."
Nonetheless, the Dictionary of the Scots Language says, under "dear,"
"Used ellipt. for dear Lord," and gives such examples as "dear bless
you," "dear keep you," and "dear help you." In particular, "6. dear kens
(knows), God knows (implying that the speaker does not)." Surely no one
ever said "The devil bless you" so I think they have a solid case with
all these variations.

I see it as a parallel to substituting "goodness" for "God", whose name
thou shalt not take in vain.

Another, much less likely suggestion I once read is that "dear me" is a
calque on Italian "dio mio". Yet another suggestion was that "the dear
knows" came from Irish "tá a fhios ag Fiadha" (Lord knows), which can be
watered down if "Fiadha" (Lord) is replaced by "fiadh" (a deer).
Some people are never content with the obvious explanation. Other
languages use the adjective "dear" in similar exclamations.

Don't forget the Third (or Second if you follow Augustine) Commandment.
As each euphemism for God's name takes on the quality of a name itself,
it requires another new euphemism. One of my great-aunts considered
"Heaven knows" outright blasphemous and even "Goodness knows"
questionable.
