Three weeks ago my sister-in-law was still pregnant. She and my brother have refused to tell anyone the names they were considering - they didn't know themselves which of the three they would use.
My sister was visiting a friend when the friend's 3 yr. old son asked her "Do you know someone named Ethan?". (Mom says the 3 yr. old doesn't know anyone named Ethan - rather unusual name in these parts)
Fast-forward two days later - my brother and sil have the baby, and announce his name is - Ethan.
