Manchu Xu's surname belongs to sinicization and changed to surname. Manchu people often take Xu's surname, and it is often the case that the same surname is different. You should first ask your grandfather or father where your hometown is, and then ask your distant relatives where the genealogy is.

There is no necessary connection between the Eight Banners and surnames, because the Eight Banners are not determined by surnames. Every flag has many big names. Sometimes my brother is in blue, and my brother may be in yellow. It is also common to move from one flag to another. In short, flags are not necessarily fixed.

You should not use the thinking concept of Han nationality to understand Manchu surnames. The surnames of the old Manchu and the Han nationality are conceptually different. The old surname in Manchu generally refers to the name of a family, which is only used when addressing this family, and is not used by individuals at ordinary times. Such an old surname will also change with the division of the family. The surname of Han nationality has only a simple function, that is, to express the blood relationship between father and son, which will not change from generation to generation, but the old surname of Manchu is not like this.
