Origin
Meaning and origin of Rosha
The surname ROSHA has its origins in the Indian subcontinent, specifically in the region now known as Punjab. It is believed to have emerged during the 16th century, derived from the Sanskrit word "rosha," which means "anger" or "fury." This suggests that the name may have originally been a descriptive surname given to someone with a fiery temperament or a warrior-like spirit.
One of the earliest recorded instances of the ROSHA surname can be found in the Mughal Empire's administrative records from the late 16th century. These records mention a certain "Rosha Khan," a local chieftain who wielded significant influence in the region.
In the 17th century, the ROSHA name appears to have spread across northern India, particularly in the areas now known as Uttar Pradesh and Rajasthan. During this time, the name underwent slight variations in spelling, such as "Rosha," "Roshaa," and "Roshahaa," reflecting regional linguistic differences.
A notable figure bearing the ROSHA surname was Hari Singh Rosha (1695-1768), a military commander who served under the Maratha Empire. His bravery and strategic acumen earned him a reputation as one of the most skilled generals of his era.
Another prominent individual with the ROSHA name was Maan Singh Rosha (1783-1846), a wealthy landowner and philanthropist from Rajasthan. He was known for his generous contributions towards the construction of schools, hospitals, and temples in his region.
In the 19th century, the ROSHA surname gained recognition in the field of literature with the birth of Gyan Chand Rosha (1825-1892), a celebrated poet and writer from Punjab. His works, which celebrated the rich cultural heritage of the region, are still widely studied and revered today.
As the British Empire expanded its influence in India, the ROSHA name found its way into colonial records, with several individuals serving in various capacities within the British Indian Army and civil administration. One such notable figure was Sardar Bakhtawar Singh Rosha (1871-1937), a highly decorated military officer who fought in multiple campaigns during World War I.
Throughout its history, the ROSHA surname has maintained its strong association with valor, leadership, and a deep connection to the cultural roots of the Indian subcontinent.

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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
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 Rosha surname at the time of the 2020 Census, not any inherent property of the name itself.
