Help!!

Shauna

So we're expecting our second child and this Saturday we find out the gender!😊 well I have back problems and this will probably be our last child.. that being said our son has my hubbys initials(both are TJD) and whatever the gender is with this one we want to use my initials(SDD). Our last name is DeWitt. Our sons name is Titus.. we love older unique names. Anyone have thoughts?? We're stumped on names. Naming our first seemed so much easier. We like Silas but idk about a middle name..
