I'm sorry I don't check this message board very often at all. I don't know if you are aware of this or not, but Walter McElreath (1867-1951) was the founder of the Atlanta Historical Society. he was raised in the Lost Mountain area and he has written an autobiography that contains much family information of the period and much geographical information about Lost Mountain. He was part of a large family with 5 brothers and 4 sisters. I'm sure you are related to him. I have a copy of this autobiography that I use for better understanding the history of the area. My email address is email@example.com
if you have any other questions that I may be able to answer.
