Dear Barney and Barbara,
In 1823 Schinkel was a village of 76 households and 562 inhabitants,
the proper catholic church parish is the cathedral (Dom) St. Peter,
the church parish Schinkel Heilig Kreuz was founded on April Day 1914
and Schinkel Ost St. Maria Rosenkranz (St. Mary s rosary) was split off
of Schinkel Holy Cross as a church parish on September Day 1921,
so I doubt that they can help you with your ancestry,
the dicesan directory of 1990 says that Schinkel-Ost has vital records since
1918,
Schinkel Holy Cross has vital records since 1914-
whereas St. Peter has baptismal records since 1653,
wedding records 1654 - 1676 and 1695 through this very day,
burial records since 1654.
Have a great weekend, greetings from Diepholz in the midst between Bremen
and Osnabrueck
