Phineas Nigellus

No: HPFGUIDX 106333

Has anybody noticed in OoP p. 826, 828 that Phineas Nigellus which is
Sirius' Great Great Grandfather, first of all has a different last
name (not Black, how can that be?) & that it is stated #1- p. 826 that
Phineas does not believe that Sirius the last of the Blacks is dead
and #2 on p.828 it is stated that he still had not returned to his
portrait in Dumbledore's Study. Why would she state that he did not
return if it wasn't significant? Did she forget, I don't think so...
Why didn't he come back? Did he find something?
