Who came up with your newborn or unborn baby name?

I’m currently 39 weeks and 2 days pregnant. My due date was December 9th, but I’m getting induced on December 6. When I was about 19 weeks pregnant we found out that we was going to have a boy. When my fiancé and I found out that we was having a boy I asked him “do you have any names in mind” He said Vicente. I said what does that means in English (my fiancé is Mexican) he said Vincent. I fell in love with that name especially when he said it in Spanish. So, we decided to have me pick rather to spell it/pronounce it the Spanish or English way and I said the Spanish way. I came up with Alejandro (his middle name) a couple of days later and we both agree on it. Who came up with your babies names? How did your babies get their names?
