I would split my winnings with my husband (1/4%), my daughter(1/4%),myself (1/4%) and split the other 1/4% with my brother and sister. The reason I'd split it this way is the taxes. There are gift taxes I'd hate to mess with. I'd not have to worry if they used the money in a way I don't like. If they used it up, too bad. My husband and I have different hobbies so if he wanted something I have no interest in, it's his money.
