Boy and Girl name, Spanish/English help!

We are trying for Baby #2 and thinking of both girl and boy names. Our last name is VERY long (12 letters, starts with T) and we nailed it with our first. Our daughter (#1) is Lucia Ezabel (Isabel is a family name; we changed spelling)= LET for initials which are a positive connotation and fun letter-combo. The name MUST be the same in English and Spanish (ie: Lucia, pronounced Lu-see-a). Also, no common names - Carlos, Luis, Maria...

Ideas so far:

Isaac Sebastian

Sebastian Edison

Stela _____
