Rathmanna is a townland containing just over 45 acres in Rahelty civil parish in County Tipperary.
[1] It should not be confused with the much larger townland of the same name just across the border in Borrisleigh civil parish.
At the time of the 1891 census, it had a population of 5; in the 1901 census, this had grown to 8 and by the 1911 census had grown again to 12.
