Frederick and Elizabeth (Seaver) Blanchard are buried, with their daughter Elizabeth, who died at age 14 months, in National City, California, and are buried in La Vista Memorial Park in National City. They are buried in the unmaintained portion of the cemetery, shown in the photo below:

This is the only record I have found for the daughter, Elizabeth Blanchard, who died at age 14 months. I have not found a birth or death record.
I discovered this gravestone by happenstance when visiting La Vista Memorial Park for the South San Diego County Graveyard Rabbit post about the cemetery. See, blogging pays off!
