The firm was George L.Hanks located on Columbus Street in Cincinnati. It was established in 1857 but I do not know how long it operated under this name. By 1857, Andrew Meneely had married Philena Hanks and the Hanks and Meneely foundry had been in operation, and the name had changed to the Meneely name. I do not know how George L. Hanks was related to either Julius Hanks or Benjamin Hanks who were also bell founders. I think he was a son of either Alpheus Hanks (uncle of Julius) or Turman (brother of Julius). They were all bell founders. Alpheus and Truman operated under the name A & T Hanks.
Benjamine Hanks learned bell founding as an apprentice in the Paul Revere bell foundry, and Julius was his son. They were all related to Nancy Hanks Lincoln, Abraham Lincoln's mother.
The Goerge L. Hanks firm made bells up to 5,000 pounds. One weighing 3,400 pounds was in St Peter in Chains Cathederal in Cincinnati and was very ornate. Later this bell was moved to St. Teresa Church in Cincinnati.
There is lots more information on the two Meneely bell foundry firms located in Troy and West Troy, N.Y. -- Neil
I collect U.S. church and fire tower bells and research the foundries which made them.
