Connie Mack - Personal Life

Personal Life

He was born in East Brookfield, Massachusetts to Irish immigrants, Michael McGillicuddy and Mary McKillop. He did not have a middle name, but many accounts erroneously give him the middle name "Alexander"; this error probably arose because his son Cornelius McGillicuddy Jr. took Alexander as his confirmation name.

In 1877, Mack left school at the age of fourteen after finishing the eighth grade. Partly this was because he needed to help support his large extended family, since his father, whose health had been ruined in the Civil War, was an alcoholic and no longer worked. Mack always regretted his lack of education and advised college players to finish their degrees before they began their baseball careers.

On November 2, 1887, he married Margaret Hogan, whom the Spencer Leader described as having "a sunny and vivacious disposition." They had three children, Earle, Roy, and Marguerite. Margaret died in December 1892 after complications from her third childbirth.

He married a second time on October 27, 1910. His second wife was Catherine (or Katharine) Holahan (or Hoolahan); the census records disagree. (The wedding register reads "Catarina Hallahan".) The couple had four daughters and a son, Cornelius Jr. A faithful Catholic his entire life, Mack was also a longtime member of the Knights of Columbus (Santa Maria Council 263 in Flourtown, Pennsylvania).

From early on in life he was known as "Mack", as his father had been. However, he never formally changed his name. On the occasion of his second marriage, at age 48, he signed the wedding register "Cornelius McGillicuddy". His nickname on the field was "Slats."
