Michael Healy was a native of Limerick and joined the Irish Volunteers in 1917 when they were being reorganised following the 1916 rising. He was promoted to Captain in the Volunteers and was heavily involved in IRA activities during the War of Independence. Healy took the Anti-Treaty side during the Civil War. He remained in the IRA following the end of the Civil War and was involved in its reorganisation until at least 1924. He appears to have been involved in helping to expedite the application process for military pensions for members of his company and battalion in c. 1940. He is recorded in 1956 in Dáil records as having been in receipt of a government pension having served in the War of Independence. Little is known about his life outside of the IRA except that he lived and worked as a shoe repairer at No. 38 Nicholas Street, Limerick City.
