Have compared the 1881 and 1891 censuses and they are the same place - same number of houses and numbers 3&5 are a Pub
. Looking at the original 1881 census sheet I think it has been wrongly transcribed as Hamank - the old style capital F and the l do look like an H. So Flamank it is! Do you need any info about the residents?
Forgot to mention that it is shown as Flamark in the 1891 census and there's no Hamark Street.
