Hi, I have no other way to do this....... my dad is John's son (so he was my grandfather). I am wondering what type of cancer did he have? Sorry, just had no idea how to find him, and I just started my search again..... and found this!
I played a lot of tennis with John and there is no doubt that I learned a lot about tennis when he was my partner and also when he was my opponent. We had many good laughs along the way, especially when he would surprise me with his underhand serve :- )
