Others would suggest the name was more related to the possibility of this little guy resembling Kevin The Bold when he grew up.
In the 1950's Kevin The Bold was a household name. Kreigh Collins developed a comic strip named Mitzi McCoy. It appeared every Sunday starting November 7, 1948. Mitzi’s ancestor from the 1500's Kevin The Bold joined the characters on September 24, 1950. Not long after the comic strip was renamed Kevin the Bold.
The story goes that the young shepherd Kevin became a trusted employee of King Henry VIII. He and his cohorts Pedro and Brett had many adventures that lasted a couple decades. Many of the strips echoed Mr. Collins own life. The Collins family took a year off and spent it sailing, and the youngest of the four sons was named Kevin.
Mom either really liked the name or hoped I would end up working for the King. Obviously any resemblance to the picture above is only accidental.
