Brennans (Brannans) documented as being born in County Roscommon, Ireland in the 1871 England Census Records

The early years of the England Census records infrequently report the County of birth in Ireland, but notation of more than just the country becomes more frequent from the 1861 census on.

Thomas Brennan, Hampshire, District 1, son of John and Sarah Jane (both British subjects), was listed as being born in Athlone. There is an Athlone in Roscommon as well as in Westmeath; however, another sibling is listed as being from Mulingar that is either in Donegal or Westmeath so I think it is unlikely that Athlone refers to Roscommon so he is not included in this compilation.

These records will be presented alphabetically by given name.

I have highlighted the first name in each residence whether it be a head of household, lodger or inmate to help differentiate the groupings.
