On the Marraige Certificate of my GGrandFather Martin Banker and My GGrand Mother Catharene Yeager as witnesses were Alfreda Banker & Bennet Banker. I believe Bennet may be his brother as I also found him in the same Civil War Unit as Martin Banker. If anyone has any information about either it would be much appreciated. They were married in Delaware County, N.Y.. I believe this is where the family is from.
