I seem to have hit a brick wall in locating Lily Hudson (b.1903 in Sheffield) on the 1921 census.
She appears on the 1911 census living with her father Frederick (1875-1927)and her 3 siblings.
Any help would be appreciated.

I think I've found her and her sister Edith living with Uncle Moses Mann, working as a bar maid in the Bell Hotel in Oldbury West Bromwich.

Hope this is the person you are looking for

This MIGHT NOT be the right person as I've just looked at the 1911 census and Edith isn't one of the siblings.

Is it just the 1921 census you are looking for? Or beyond 1921 too?

I can't confidently locate her in 1921 either. Some sources (e.g. a FamilySeach.org tree) say her mother died in 1909. This may have broken up the family.

Yes ,the family did split,and we have her details after 1921,it is just in 1921 that she seems to be missing from the census.
