The Wayne records do show the second child for Seth and Polly Knowlton Billington, both children with the same birth date(twins). However in Northwood I did not find any child but Ruth. At one time the birth of Ruth was in the card file records at the NH State Vrs but she is now missing and I need to look at the film that is available there of birth records and possibly the second child is listed there also. The NH state Library index for all Town Records does not show any births to the couple but does list their marriage.Further the IGI shows them with an Olive Ann and I do not have any idea how that came about. The Northwood records are also difficult births marriages and deaths are entered in between town meetings androad surveys.
