Is "if I good remember" sentence correct?

[nyota]

Are you sure you're not hearing "If I could ​remember ..."?

I say "If I remember rightly ..." - the phrase used by members of both sides of my family and so the one I grew up hearing.

I'm a bit confused, I thought rightly means justly or sensibly? I feel in your example it's to mean correctly, therefore, shouldn't it be right?
