I can't post this on her actual birthday since it doesn't exist, but the U.S.'s previous President has another daughter that a lot of us don't know about. Her name is Ryan Laura Bush (her middle name is after her mother, which she frequently uses like many other female Ryans so people don't constantly assume that she's a he). What's really unique is the day she was born: February 30, 1984. February 30 is also a special day for George W. Bush for this reason.
As for what Ryan Bush is up to, she's planning on running to be the first member of Congress from the Millennial generation (1982-sometime in the early-mid 20-aughts) in 2012.
If you haven't realized, this whole post is made-up (hence the February 30 birthday, based on Dubya's blunder in that video). I made it up as a joke to this thread on Nameberry when one of the members gave out "Natal Flower Names" based on the birthday of the person in question (if the link doesn't take you to the right post on the page, it's the third from the bottom; the first post on the next page is the OP of that thread's response to my joke). If it were real, that might explain the rise in female Ryans born during Bush 43's administration.
