Alfred the Great lives to 80

Just saw Alfred died relatively early at age 50, likely due to an illness. What happens if he lives to be 80? ITTL he lives exactly 30 years longer than IOTL and dies of natural causes.
 
I suppose he would be the first king of England followed by his otl Grandson

I suppose a big impact would be that his eldest grandson has children unlike otl and that Alfred establishes the identity of England

As a permanent political entity earlier than otl
