Orangello and Lemongello are urban myths. If anyone personally knows folks with these names, I'd love to hear it.
Can't speak to these two names. But my sister-in-law was a social worker in a child's nursing center. The Fe-ma-le name has been used several times.
Back in 1971 I met very tall black student at SU and his name was pronounced Lemonjello...not sure how he spelled it though.It's foggy, but it may have been his last name.
No urban myth, I worked for a dentist in high school. Two of his patients were twins, oranjello and lemonjello. Cute little identical boys. Lots of fun.
There is a white family quite well educated who named their son Braxton Hicks! I dunno--maybe she was in labor a little too long.
