SNGF: Ahnentafel Roulette

Once again, Randy Seaver of Geneamusings blog, has posted his Saturday Night Genealogy Fun (SNGF) challenge, and I'm tired enough from gardening to need some respite. So.....

1. What year was one of your great-grandfathers born? Divide this number by 80 and round that number off to the nearest whole number. This is your "roulette number."

My father's father's father, Alvah Clyde SHARP, was born in 1871. 1871/80 = 23.39, rounded off to 23. I'm beginning to suspect that everyone's number is going to be 23.

2. Find the person in your ahnentafel chart with that number. Who is that person and what is her vital information?

Number 23 is my father's mother's mother's mother, Elizabeth MOHR, b. 17 Dec 1838 in Germany, d. 1 Mar 1888 in Houston, Texas. She married Herman SONNEN in New Orleans, Louisiana, ca. 1858.

3. Tell us three facts about that person.
4. Write about it in a blog post....

I don't know a lot about Elizabeth, but I'll see if I can come up with 3 facts.
   * Elizabeth and Herman had at least 9 children born between 1860 and 1879.
   * The family moved from New Orleans to Houston between February 1871 and March 1873, based on children's birthdates.
   * Elizabeth is buried in the family plot in Washington Cemetery, Houston, Texas. Her maiden name is misspelled "Moore" on the tombstone.
   * At the time of Elizabeth's death in 1888, she apparently still had relatives living in New Orleans and St. Louis, Missouri, as her very short obituary in the Houston Post ends with "New Orleans and St. Louis papers please copy."

I have tried numerous times over the years to identify Elizabeth's family with no success. If anyone has any suggestions for finding them, please let me know.
