There is a misprint in this newspaper article. Pictured with Jack Gibbons are Jack's younger brothers Gene, Danny and Jimmy who are also sons of Mike Gibbons and not Jack's cousins and sons of Tommy Gibbons as the article states. Caption at the bottom reads:

TO MANY OLD TIME FIGHT fans it does not seem so long ago that Mike and Tommy Gibbons were youngsters fighting and beating the top notchers of their weights; but now we are in the second generation. Here are the sons of Tommy Gibbons telling the son of Mike Gibbons what to do about his fight with Freddie Lenhart of Tacoma in the St. Paul Auditorium Friday night. Jack is taking it in too. Seated around the now famous light heavyweight are, left to right, cousins Eugene, Danny and Jimmy. Jimmy is saying, "Use that right hand some more next time. It's a dandy."
