It's Willie Clark, the young clerk on who's bed the President was cared for and died at Petersen House. Willie was away when the President was shot.

Here's a link to images of a letter written after the assassination where the former letter to Ella is mentioned:

Willie later married Ella.

Note: There are a couple of forged letters by an Augustus Clark (as an alleged roommate of Willie) which claim to be an eyewitness account of Lincoln's death at Petersen House but were in fact written years later.
