The more you get into genealogy, the more often you will find errors in information. Perhaps the person just hit the wrong number, or perhaps he/she made it up - or anything in between. When you get information from sources other than primary sources (birth certificates, death registrations, etc etc) you need to look at it as a possible sign post to your family, not as FACTS. Even with primary sources, there can be errors (somebody typed in a wrong date, a grave stone has the wrong date on it, etc) so it is suggested that you find about three different sources for your information. Use the sign posts, but back them up with your own research. Grandma or Aunt Susie - or Ancestry.com - may have it wrong. It is really annoying to follow a lead, then find that it's not your family that you have been following. You DEFINITELY need to double check Capt William WILKINS' information. Certainly an error there somewhere.
