While working some duplicate profiles within the family of [[Harding-4|US President Warren Harding]], I noted that many of the family members have "nicknames". However, I have been able to account for all of the siblings of the President, leaving this one, Birdie, as disproven. The original disproven note was put on this profile in 2012.
I made the original assumption that this was just a person attached to the incorrect parents, but after a thorough search of Ancestry.com and Family Search for records, there were known supporting a person by this name with these dates.
After a lengthy search of the web for ANY evidence of Birdie's existence, I can ONLY find numerous unsourced family trees that list her as a sister of the president with these dates.
