Oh, i have also heard this and through much searching, have come to the conclusion it was Anders Andersson, who was supposed to be on the deck with his family as Titanic sank.
Even with the Anderssons not surviving, as they were last seen on the boat deck and should be still there as the Titanic sank and its boat deck flooded, their remains should be found, but none of the their remains were identified as theirs. Perhaps they went below the boat deck after being last seen alive or weren't wearing lifejackets.
For the parents and the 2 older daughters (should be old enough to be wearing lifejackets and/ or recovered unidentified), it might be possible they entered the ocean with a lifejacket and off the Titanic, but their remains drifted off without recovery or could be recovered unidentified based on the link below.
Note that the father, Anders Andersson (
Unidentified Man on Collapsible B), might be the unidentified man on
Collapsible B or body 104 (identified by Encyclopedia Titanica as Alessandro Pedrini, but identification as Pedrini, Andersson or somebody else is questionable based on the link below and the body's burial at sea), the mother, Alfrieda Andersson, might be either one of unidentified bodies 5, 13, 54 or 210, but identification with DNA might be needed on bodies 5, 13 and 210 at Halifax first, and either 1 of the 2 older daughters (more likely the elder daughter Sigrid) might be body 328 (identified as Hileni Zabour, but still listed as unidentified, so, identification with DNA at Halifax might be needed to proof the body's identity as Zabour, Andersson or somebody else, body 328's facial and skin features might have darkened to dark due to decomposing and 4 feet 6 inches should be a 9-11 year old's height, not a 14 year old's).
