Thank you. I was just going to post exactly this. In addition, Cecilia also had international success before 1936. She was 12 when she won the 1933 European silver medal and 14 when she won the World silver medal behind Henie in 1935. As you mentioned, Megan was 13 when she was second at 1934 Worlds behind Henie. Hilde Holovsky was also 13 when she won World silver in 1931.
Little girls achieving great things on competitive ice has a long history!
And everyone seems to forget that Mirai Nagasu won the National Championship when she was just 14--a year older than Alysa. Michelle Kwan won silver at Nationals at age 13--and arguably should have had gold after Tonya Harding was stripped of her title.
