I relied mainly on other family tree data for the dates of birth and death. I have verified my 4th great grandfather, David Smith, was born August 1, 1801 in Connecticut and died in Winnebago County, Illinois. I could not verify any information on his supposed father Grove Smith born 1775 in Connecticut and died 1818 in Ontario Canada or his mother Rebecca Tobyne 1776-1818. When trying to verify her parentage, the family tree data had her father as 11 years old and her mother as 9 years old at the time of her birth. Obviously that data is wrong.
