Not sure why they didn't find it.
But the name indexed is Calipo Francesco Antonio. Do you think that they were looking for a person whose first name was Calipo rather then vice versa? Most name are liste first and last, not last then first.
Did they look by date for the entire month? One year before, one year after?
They are living in Hawkins, Tenn. Any chance they married in Tennesse rather then VA? Long shot, I know.
Will see what might be out there. In 1910, he is listed as Frank Francisco in the census. So apparently, they were having problems with the name as well
