I watched something the other day and the Mom said the first one was a J name and then the second. After that, they thought the next one may be the last one and didn't want them to be left out of the J theme, so another J name. This continued with each baby, not wanting that child to be the last and be the only one without a J name. I suppose if they'd have known at baby number 3 that they'd have 18, maybe they could have switched up, LOL!
