After George’s death in 1945, Eliza remarried to Albert Collonson (unconfirmed). Arthur was second son.
Sadly George and Arthur died within a couple of days of each other

On 17th Inst., in hospital, ARTHUR, beloved son of Eliza BROWN and the late George Harry, age 20. At rest. Service Christ Church, ? p.m. Interment Weaste Cemetery, 3 p.m. to-morrow (Thursday).—2, Windsor Terrace, Salford 5. Inq. Pendleton Co-op.
I only have the transcript from BNA, which is OCR generated, best I can do.
Extremely sad.
From deceased online free index, both George and Arthur were buried 19 April at Weaste. Probably together, there is one other in the grave.
So, if it is confirmed that Annie died in the Salford area, Weaste is certainly one place to look for a burial.
