Robin,
I profiled Walker in a book covering field grade officers interred in Hollywood and was provided a copy of an image of Mrs. Wlaker and three of their four children that he was purported to be carrying when he received his mortal wound. I also received a copy of a portrait of Walker that hangs in the family home today. I am writing you from memory (because I am out of town), so I do not recall whom I talked with in the family a few years back.
Sincerely,
Chris Ferguson
