Banker Family Genealogy Forum
You should check the Social Security Death Index. Go to www.ancestry.com, and you'll find a link to the Index. Type in George Banker's name, and MI for the state. You'll find information on George (b. 1896, d. 1979), and information on how you can send for copies of his social security application, which might list more of his family line.
If your Bankers are from New York, they're not the same as mine (which are from Germany in 1728, and into Maryland in the 1750s); there may be some connection way back, however.
