I did a check of the easy data bases I have and came up with 23 Coopers. Edmund B. Cooper (1824-1911) and his older son Frank a pilot (1857-1923) and Earl a Capt, (1877-1955) is about the only family I found. I have not look at my books of steamboat licenses to see what is there. To put families together one has to go to the census or to public family trees, or Family search and hope some one has done the work.
