the big lottery winner putting her big family first. Paying off a promise from the mother they loved. One sister actually had the $20 million ticket but tonight, her siblings are becomicg rh, too. Here's ABC's linsey Davis. Reporter: Meet the endresons of New Jersey. A whole bunch of them. This is a large family that won. Reporter: Thanks to a little luck and their mother, flossie. My mother started this tradition years ago. She said, you know, I have 19 children. How am I going to afford to leave you much? So, she said, my only chances would be with the lottery. Reporter: Even after flossie died, her kids kept up the tradition. And they finally hit the jackpot. $20 million. There's Jonas and Marie. That's John and faith. In all, there are 17 brothers and sisters, ranging from 53 to 76, plus the three children of a sibling who died a few years ago. They'll all be splitting the jackpot, 20 ways. It was Sigrid who bought the winning ticket. She went to the local 7-levieleven because her niece was low on milk and bought a pick six ticket. I started to cry and I called my sister to come and get me. Reporter: So, now all the siblings get a piece of the pie. Their mother even devised a plan for how they'd split their winnings. I'm 76 and I worked very hard my whole life. This is just a wonderful icing on the cake. It took two weeks before it sunk in. I went to sears and bought a new pair of work boots. Reporter: Many of the family still plans on working and playing the lotto the same way they do everything else -- as a family. Linsey Davis, ABC news, new York.
