Origin
Meaning and origin of Malamphy
The surname Malamphy has its origins in the English counties of Nottinghamshire and Derbyshire, where it first appeared in written records during the late 13th century. The name is derived from the Old English words "mala" meaning "speech" and "manpig" meaning "impudent", suggesting it may have originally referred to someone who was outspoken or brazen in their manner of speech.
One of the earliest recorded instances of the name is found in the Hundred Rolls of Derbyshire from 1273, where a William Malamanpig is listed as a landowner in the village of Wingerworth. The spelling of the name evolved over time, with variations such as Malamphie, Malamphi, and eventually, Malamphy appearing in various records throughout the medieval period.
During the reign of Edward III in the 14th century, a John Malamphy is mentioned in the Patent Rolls for Nottinghamshire, having been granted a license to hunt in the royal forests of Sherwood and Clumber. This suggests that the Malamphy family had attained a certain degree of status and privilege in the region at that time.
In the 16th century, a notable figure named Thomas Malamphy (1510-1582) was a wealthy merchant and landowner in the city of Nottingham. He is recorded as having donated funds for the construction of the city's historic Trent Bridge, which still stands today.
Another prominent individual bearing the name was Sir William Malamphy (1628-1701), a member of the English gentry who served as a Member of Parliament for Nottinghamshire in the late 17th century. He was also a notable patron of the arts and commissioned several works of architecture and sculpture for his estate in the village of Southwell.
In the 19th century, the Reverend Edward Malamphy (1793-1864) was a respected Anglican clergyman who served as the Vicar of Bakewell in Derbyshire. He was known for his charitable works and advocacy for education in the local community.
While the name Malamphy is relatively uncommon today, it has a rich history and connections to various localities in the English Midlands, particularly Nottinghamshire and Derbyshire, where it originated and flourished over the centuries.

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.

Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Malamphy surname at the time of the 2020 Census, not any inherent property of the name itself.
