Thanks to someone who bought the house that belonged to my father's father, I have been able to go through some items that have helped me piece together the relationship between Ernest Sommer Brogdon and Ernest Chalmers Brogdon.
Of course, the information did not give me a new lead, but it did help me to find pictures and piece together the fabric of their lives. I did find long sought after pictures of Ernest Chalmers B. and that was worth it.
There is so much now that is apparent to me in the long saga of this story and I will be processing it for some time. However, don't give up on these "brick walls"--whatever they may be. It was through these postings that someone contacted me. It's been eleven years!
