I believe there are only two this year, however you are on track with the best performing families in the derby. Female family 1 the only contender is fast and accurate and he comes from family 1-W. The best Family 1 is actually 1-X, however there are none with 1-X. The only contender with 23-b is gormley. If you pull up
www.pedigreequery.com, you will see a search box around the top left of the page. Type in the horses name and hit search. The horses breeding will come up. If there are a number of horses with the same name, you will have to click on the one that says USA 2014. When the info comes up you will see the horses name and the year 2014 next to it. To the right of the year you will see in parentheses with the number of the female family. It's fairly easy. The number refers to the female family pedigree at the very bottom of the page and should be colored in all pink. Let me know if that's what you're looking for or if you need additional info.
