In 1953, Margaret and Alexander Bow of Ypsilanti, Michigan, welcomed their 15th child, a baby boy.
He was given the name Amen — from amen, the word used to end Judeo-Christian prayers — even though the couple expected to have more children.
(I don’t know if they ended up having more, but two of the older children were named Mary and Winifred according to the 1930 census.)

Interesting side note: if you google, you’ll find a family tree listing this guy. To go by that, he only had one kid, who has a totally normal name.
