Who originally owned Dobby?

I searched for this and couldn't find any info - maybe someone here
has a theory.

Why did Dobby originally care so much about Harry Potter? He was
"owned" by the Malfoys - aren't house elves supposed to show loyalty
only to their masters?

I theorized, originally, that Dobby was owned by the Potters and was
"taken" by the Malfoys after the Potters were killed, hence he
would've had an affinity for Harry. I thought JKR would bring this to
light in the 7th book but she didn't.

So why did Dobby care about Harry at all, then? Isn't that off the
charts for a house elf to be?
