??? ?? in the Marriage 48 Years 11 Months. She birthed 11 Children of Whom still 9 are living 6 Sons 3 Daughters.  She Died 4 May 1798 Her age was 67 Years 6 Months 3 Weeks 2 Days.

The first line of Anna's stone appears not to have been readable.  Apparent mis-readings:  "inder" should be "in der" (in the); "Eh." should be "Ehe" (marriage); "Zevgte" should be "Zeugte" (begat, fathered); "v." should be "u." = "und" (and), but note that in stone carving, "u" is often rendered "v," I presume because it's easier to carve.
