2011's Most Popular Baby Names: Credit Kardashians? Sophia, Jacob come in first, but Mason is No. 2 for boys By Evann Gastaldo, Newser Staff Posted May 14, 2012 9:35 AM CDT 5 comments Comments Sophia and Jacob were the most popular baby names last year. (Shutterstock) (Newser) – Jacob continues to dominate in the land of boy baby names, taking the No. 1 spot for the 13th year in a row. But there's a new winner in the female category: After two years atop the list, Isabella has now been replaced by Sophia. Isabella was downgraded to second place, followed by Emma (which was briefly No. 1), Olivia, and Ava. For boys, Mason was No. 2 (it jumped 10 spots—thanks to the Kardashians?), followed by William, Jayden, and Noah. The AP notes that Michael took 6th, its lowest ranking since 1948. Mason isn’t the only reality TV-influenced name making waves on the list: Briella was last year’s quickest rising female name, jumping 394 spots, perhaps thanks to Jerseylicious and Glam Fairy star Briella Calafiore. For boys, the fastest rising name was Brantley, perhaps due to country singer Brantley Gilbert. Click for more, including the boy's and girl's names that took the biggest fall.
