McManus Surname in Ireland
The Griffith Valuation was a survey done in the years from
1848-1864 of everyone who owned and/or rented
land in Ireland. Since no census records of
Ireland exist for this time period, the Griffith
Valuation is the only way of learning who lived
where in Ireland at that time.
The map above shows the distribution of the
surname McManus in Ireland in the mid-1800s as
listed in the Griffith Valuation of Ireland. The
color of a county indicates the how many
McManus were listed as residing there in the
mid-1800s. Bright green indicates the counties
that had the largest number of McManus'. Lighter
shades of green indicate counties containing fewer
McManu', while dark gray and light gray indicate
counties with even fewer McManus'. Counties that
contained less than 55 McManus' are not colored -
so the map only shows where 85% of the McManus'
were living.
According to the
historical account
the McManus name originated in groups in County Fermanagh and County Rosommon. This agrees
roughly with the distribution shown in the map.
There were 1300 people listed in the Valuation
with the surname of McManus - and almost a third of
these of these were in County Fermanagh.
