The marriage date is from the "Dodge County Marriage Book 1871-1966" and the death date from "Dodge County Newspaper Clippings" both by Tad Evans. I'll be happy to do any look-ups you might need.
Yes, I would love to see a copy of the death certificate.
I have seen many birthdates that don't agree with the tombstones. I usually go with the earliest census date found and chalk up the incorrect date on the tombstone as because the survivors didn't realy know when the person was born. Some of the info found in family Bible also has to be taken with a grain of salt. I know that there is one floating around where the people all died l to 2 years later than their published orbits. Some family Bibles were created or doctored after Social Security was introduced. Few people born in Ga before 1925 had birth certificates and as family Bibles could be used to get a "delayed birth certificate" there was some families that brought the Bibles "up to date" or suddenly "discovered" a Bible that listed their birth.
As to Susan's tombstone: The person who cut the stone probably couldn't spell "worth a toot" and no one noticed. I suppose that Susan's children buried her, so as she had only been married to Tripp for a couple of years and had no children by him, they buried her under the family name. The same thing has happened in my family.
