Okay-- another UPDATE to my Previous UPDATE!!
Dr. William BAIRD & Ellie Ann DAY only had 2 children: Henry Lewis BAIRD & Laura Belle BAIRD.
The other children I listed: Sarah, I believe is actually Laura with the wrong name listed on the census.
Ella C. DAY, was from either a previous marriage that I haven't found record of or she was born out of wedlock. I can't find record of Ellie Ann DAY's family between the 1850 to 1870 Federal Census. So, they may have left Person Co., NC during that time period.
Graham was born after William BAIRD died (and longer than 9 months later). I am unsure if he is her child or not.
