Ladd at Deathbed?

[Dan Pearson]

Below is a link to a story about one Major Jonathan Ladd of Lowell, Massachusetts, who, the article claims, may have been present at the deathbed of Abraham Lincoln. Without having the time at present to look into the story further, has anyone any information about such a person having been present at that moment?
