Not related to me, but a childhood friend of mine is the grandson of Weldon Wyckoff, a pitcher on a few of Connie Mack's Philadelphia A's teams in the mid 1910's. To my knowledge, the only card he appeared on was the 1913 T200 Fatima Team Card (sitting to Chief Bender's left). If anyone knows of any others, please let me know. I have picked up a few Fatimas for him and his dad (Weldon's son) in the past, which blew their collective minds.
