Origin
Meaning and origin of Magrann
The surname Magrann is believed to have originated in Ireland, tracing its roots back to the ancient Gaelic language. The name is thought to be a variant of the Irish surname Ó Magranna, which means "descendant of Magranna." Magranna itself is derived from the Old Irish personal name Magrán, which may have been a diminutive form of the name Mógr.
One of the earliest recorded instances of the name Magrann can be found in the Annals of Ulster, a chronicle of medieval Irish history compiled by monks in the late 15th century. The Annals mention a man named Magrann Ua Murchadha, who was recorded as being involved in a battle in the year 1173 AD.
In the 16th century, the name appeared in the Fiants of the Tudor Sovereigns, a collection of administrative records from the Tudor period in Ireland. These records document a John Magrann who was granted land in County Louth in the year 1552.
The Magrann surname has also been linked to various place names in Ireland, such as Magranhill in County Leitrim and Magranstown in County Kildare. These place names likely derived from individuals bearing the Magrann surname who resided in or owned land in those areas.
Notable individuals with the surname Magrann throughout history include:
1. Patrick Magrann (c. 1760 - c. 1840), an Irish rebel who fought in the Irish Rebellion of 1798.
2. Michael Magrann (1802 - 1879), an Irish-born American politician who served as Mayor of San Francisco from 1856 to 1857.
3. Bridget Magrann (1846 - 1924), an Irish immigrant to the United States who became a prominent labor activist and organizer in the late 19th century.
4. John Magrann (1870 - 1942), an Irish-born Australian politician who served as a member of the Australian House of Representatives for the Labor Party.
5. Mary Magrann (1901 - 1976), an Irish-American author and journalist known for her novels depicting life in Irish immigrant communities in the United States.
While the Magrann surname may have evolved over time and spread to different parts of the world, its origins can be traced back to the ancient Gaelic language and the rich history of Ireland.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
