Boy name! Help!

My husband loves the name Santiago. He is Hispanic. I don't know how to change his mind. We have girls so far, Alexandra and Daniella. I don't see Santiago fitting in the name bunch. Anywho, he backed down to Jose (Junior) Santiago when we had our second, thinking it would be a boy. I knew it was a girl so I agreed, now I am completely unsure on it but he will not discuss names anymore. We are not sure, yet, that it is a boy so I have not pressed the issue. But, we find out at the end of the month and I want ideas for names that he might consider. My stubborn husband doesn't want typical names (i.e. kaden, landon, Lincoln), odd considering our daughters' names. Thank you much!
