so named

Last night we were looking at the proofs of Leo's school pictures and he was naming all of the kids in the group shot. He was using first names only until he got to Cecily, and then he said, "That's Cecily M_____." We were surprised, not knowing he knew her full name. We said, "Yes that's her whole name, what's your whole name?" He replied, "L. E. O. William Dougan." Guess we should start calling him by his actual name more often.
