When and where did Henry’s wife die?
Have you found Eliza Williams on the 1891 census? She’s not with her married daughter Emma Lusty and family

I wondered about this entry but he can be ruled out
Henry Williams Age 57
Estimated Birth Year abt 1829
Registration Quarter Sep 1886 Gloucester Volume 6a Page 173
PROBATE - occupation blacksmith, wife was Eliza Tucker Williams
Could either of these entries be a possibility?

Registration Quarter Dec 1898 Gloucester Volume 6a Page 159
Henry Williams Age 58
Estimated Birth Year abt 1829
Registration Quarter Sep 1887 Gloucester Volume 6a Page 166
