I found another Family Tree on Ancestry.com regarding your Henry Hardy Poore b. 1879 and d. 1922 in Anderson County, TN. You might want to search for this family tree and collaborate with the person who submitted it.
I'm a little confused on why you posted this query on the Gooding County, Idaho Message Board. Henry was born and died in Anderson Co., TN.
I didn't find anything else regarding Henry. Successful Searching!
