Hello Shirley,

the marriage record is filmed by LDS. The infos available online are:
Batchnumber: M99190-4
Groom's Name: Conradum Scherrer
Bride's Name: Mariam Elisbetham Fischer
Marriage Date: 03 Jul 1865
Marriage Place: Roemisch-Katholische,Hoerdt,Pfalz,Bavaria

About Hoerdt:
Since end of WWII the district 'Pfalz' is no longer an area of Bavaria, since then its in Rheinland-Pfalz (Rhineland-Palatinate).

About graves in Germany:
Graves are usually rented for a certain period of time, maybe 15 to 40 years. The length of time that a grave can be 'leased' varies from place to place in Germany. So don't be surprised to discover that you cannot find the grave
of an ancestor or other family member, even if that person is known to have died and been buried there.

Hope this helps.

Kind regards
Bea
