TMZ has learned that Anna Nicole Smith's sister Donna Hogan just jetted off to the Bahamas with her three children to visit the grave of her DDS -- dear departed sister.

We're told Donna went to the Bahamas in March for the funeral but the buzz is that sis may actually have been denied access to service and the gravesite.

Talk about bad blood!
