I have been able to link my family name "Ervin"( or Irvin, Irvine, Ervan, Irwin) back to the 1850's US Federal Census. I am unable to verify any information past that date. Mailing due to the census lack of information during that time period. To make matters more confusing there are several people with the same name. It makes validating very difficult :( Can anyone suggest other ways to link family other than the census?
