Hi - I'm not sure what information you need on WILLIAM HENRY ELDRED. I found him on the 1900 thru 1940 Census; his World War I and World War II Draft Registration Cards and his grave marker on findagrave.com.
If you will go to the website "findagrave.com" and type in his "memorial number" (79737517) you will be able to see a picture of he and SARAH's grave marker.
According to his World War I and World War II Registration Cards, he was born on June 23, 1883 in Aurora, Waushara Co., Wisconsin. According to his grave marker he died on Oct. 13, 1958 - he and SARAH are buried in the Pinecrest Memorial Park Cemetery in Sandpoint, Bonner Co., Idaho.
Please let me know if you need the detailed information from the Census records and his Draft Registration Cards.
I hope this helps you in your search! Sincerely, Melinda
