MacSheehy Coat of Arms and Surname Origin

Whether you spell it MacSheehy or Sheehy, the story begins in the same place. Taken at its root, MacSheehy points to “Son of Sítheach ("peaceful")”. The Mac in front of the name is a particle that was often added to Sheehy in records. Spellings drifted because names were written down by ear in parish books, tax rolls and passenger lists. You may also find the name written Shehy and Sheahy.
