I have no knowledge of any of my family members being professional sports figures. However, I did have an uncle in-law, who played for the Yankees.
His name was John Loyko. He is someone who had great promise, served his country in the Korean war, and played ball on the farm team of the Yankees. His later life was tragic, and was held up as someone not to emulate.
He died before I married into the family. I never knew him, but thought he should be in the one world tree, so I created a profile for him. To my surprise, he is now Loyko-1. Interestingly, he is now the only person on Wiki that my ex-husband is related to. (He is no longer related to me.) I will leave it to others to connect more of the family.
The phrase I think of with uncle John is "I coulda been a contender". There was a time, when he was the shining light of the family, when he played for the Yankees.
