I think there was a time when Mason held the record for consecutive birdies at the Masters. I think the number might have been 6.
His oldest son, Mason, Jr. worked for me at one time and was an excellent salesman and golfer. Another son, whose name I don't recall, was a professional golfer and was once invited by Arnie to play in his Bay Hill tournament. He played quite well and was on TV on Saturday. I suspected that he was invited because of Arnie's friendship with has dad. Later he was a club pro in Charlotte. Sadly, he and 2 or 3 friends were killed in a helicopter crash when returning home from a NASCAR race in Charlotte. They had won the chopper ride in some kind of contest.
