I've never been able to find a source for the father of Dora. I believe the spelling of her last name at birth was Magowan, but it could have been Macgowan, or another variation.
Since she was born in 1891, in China, I don't think there are many sources available. I've tried Family Search and Ancestry, with no success. She passed away in Arizona in the 1980s, and to my knowledge never had children. Since her grandfather was a missionary, I searched records for any Magowan/Macgowan surname, and none mentioned her mother or Dora. Dora was probably adopted by her step-father, so her last name in some places prior to her marriage was given as Emens.
Does anyone have any ideas about where I could look?
