Hi,
On Ellen's Birth Certificate her parents are listed as Wilkie and McDonald. This is where the birth place of David is noted. As I mentioned before David Francis was born in Pitt St. I have found a record illustrating Pitt Street about this time and there is a baker by the name of Wilkie mentioned. Next door to the bakery was the Free Presbyterian Church. His Marriage Certificate does not give a surname but his death Certificate and those of his children show Wilkie and McDonald.
Janet Wilkie's Death Certificate given James McDonald as her father. David's Death Certificate show James Wilkie as his father.
Maybe the minister was a little slack.
