It might be that Henry or William Henry NIBLETT could be the son of Samuel & Harriet NIBLETT/ NIBLET found in the 1861 Census. Unfortunately the 1891 Census image on Ancestry.com of Bertha NIBLETT and family is missing, and despite several notifications to Ancestry.com, this error has not been rectified. All I can gather about this family is that no husband was present, only the lodger Arthur John ROBERTS. What I can say for certain is that by the 1901 Census, Bertha and Arthur John ROBERTS were married.
I'll have to go back and try and find Henry in the 1891 Census, unless of course he was already deceased by this time - having the missing image would be of great help. But I'm not holding my breath when it comes to Ancestry.com correcting this error.
Thanks for your help, by the way.
Don.
