Hello, this is very interesting. We do have a Cecilia Gardner Born 1840 died August 16, 1878 in our family tomb. As for her maiden name, it was not shown. She was my great great grandmother. Her son William Innocent Gardner was my great grandfather and his son Charles Augustus Gardner was my grandfather. Now on my grandfathers birth certificated states "Charles Augustus Gardner" (not Carlos Augusto Antonio Gardner) was born at 7B Caine Road, Hong Kong.
I have been trying to find Cecilia's maiden name and also where her husband was buried. He is not in our "Gardner" tomb.
