As she was a widow, the marriage and children info should not be listed, which I guess is why it's been crossed out. A common misunderstanding in 1911.
She certainly had 10 children, registered Harrison/Saffin. This doesn't include Arthur Adolphus and probably 3 others listed as Saffin no mmn. The 2 youngest are in institutions in 1911.
With no marriage George could be a dead end.
