years of age.
- The 1850 US Census listed a "Robert B. Banks" with
information that fit all the known information on "Robert
P. Banks", thus the middle initial of "B" on the census
entry form was probably an error that should have been
"P".

have been an error since other Census records indicate the birth year
as ca.1803-1805.

- Per 1870 Census Robert P. was 66 years of age at the time.
