Harold Earl Babb

Harold Earl Babb (1-2-2-2-4-3-8=5-6) was born to Uriah Mack Babb & Jennie VanKirk Beazell on 03 APR 1917 in Chillicothe, Livingston, Missouri, USA. He died on 01 JAN 1989 in Jefferson City, Cole, Missouri, USA. His line reads as follows:

Harold Earl, Uriah Mack, George Washington, Archibald, Abner, Peter, Thomas Jr, Thomas Sr, Phillip Babb of the Isles of Shoals.

At times Harold is simply referred to as Earl. He served in the Military in WWII and by 1950 had become the Manager of a “Retail Gas & Oil Station” in Brookfield, MO. It seems that this would be the Sinclair Station mentioned on the pen.
