Surname O'Cosgras - Meaning and Origin

all surnames with 'O'

O'Cosgras: What does the surname O'Cosgras mean?

The Irish surname O’Cosgras (sometimes spelled O’Cosgrave) is derived from the Gaelic word “cosgar” which translates as “victorious”. It is an anglicized version of the original Irish name O’Cosgraigh, which is an old Irish personal name composed of the elements “cos”, meaning “victorious”, and “graighe”, meaning “spear”.

It is thought that the O'Cosgras originates from an ancient tribe of warriors who lived in what is now County Leitrim. This tribe was led by a warrior named Cosgras, and the O'Cosgras surname is thought to have been taken from him.

The O'Cosgras clan is thought to have been one of the most powerful clans in Leitrim and their influence and power extended all the way to Dublin. They were also staunchly Catholic and fought against the English initially, however when the English put down the 1641 rebellion, the O’Cosgras switch loyalties and fought for the English.

Throughout the centuries, the O’Cosgras have continued to remain prominent in the region, and today it is still a popular name in Ireland. In more recent times, the name has spread to other countries around the world, with people tracing their roots back to the original Irish heritage.
