Mary Ann's lineage has not been determined but is placed here according to one theory until more information has been found. However, if her birth date is correct, her mother could not have been Catherine Miller. There seems to have been a close association with the family of "Black" Adam Zumwalt so she may belong closer to them.
The Burket Family site says:
"The working hypothesis of this author (WLM) until more definitive data emerges is that Mary Ann Zumwalt Burket was the daughter of a Jacob Zumwalt, either Jacob Zumwalt the elder, most likely with wife Catherine Miller Zumwalt, or a Jacob Zumwalt Jr., son of the elder Jacob. The movement from the St. Charles District to CallawayCo of the Burket family coincides closely with that of the elder Jacob Zumwalt and relations described above. The marriage of Mary Ann Zumwalt and David Burket in 1817/1818 is the time in which the elder Jacob Zumwalt sold his O'Fallon homestead at Ft. Zumwalt to Nathan Heald and apparently moved to CallawayCo."
