I'm Greg's niece, and I'm quite the beginning researcher,(and so my uncle has given me lots of help!), but I just did a search and found the records to which Mike referred.They appear to be on the LDS search web site at:
I found 2 records for each "item" because of spelling or date variations.You can search for the name variations listed below.Enter the "Place" as "Germany" when searching and type in the name as indicated.I didn't select or enter any other criteria.For Matthias, I ended up searching under "Johann Joachim" and it took awhile to find the other variations coming up.There may be others, but after 50+ pages of other Johanns (Johann Martin, etc.), I think it was, I stopped for now!
- Johann Matthäus Jochem - Johann Matthes Jochum - Johann Matthias Joachim - Johann Mattheis Jochem - Johann Mattheus Jochem
- Maria Barbara Ungefehr - Maria Barbara Ohngefehr
- Valentin Jochem (one record with father listed as "Johann Mattheus Jochem," and one record with father listed as "Johann Mattheis Jochem") (Also: One record lists Valentin's date of birth as 08 Feb 1722, and the other has it listed as 08 Sep 1722.)
- Philip Paul Jochem (one record with father listed as "Johann Matthäus Jochem," and one record with father listed as "Johann Matthäß Jochem."
On each results page, the FamilySearch.org site lists information about the record collection: https://wiki.familysearch.org/en/Germany_Vital_Records_Index_(FamilySearch_Historical_Records)
Hope this helps, even though you have probably already found it by now!
