Hi Manfred:
This appears to be the case. And it makes sense when you consider Alida Graas was baptized on 19 January 1745, and a few months later, on 17 April 1745, the child passed away and the burial impost was recorded.
Wished I could have located Hermen's marriage record, but we now have another family member to contemplate: Engelbertus Graas, the man whose name appeared as a baptismal witness.
According to FamilySearch, I think I may found the municipality: Ochtrup, Westfalen, Preußen, Germany. There are Taufen, Heiraten, Tote 1667-1809 to go through. Unfortunately, I have to go to a public library in Rochester to hunt down any possible records. Again, all of this is preliminary speculation. The only online resource was here (Matricula One): https://data.matricula-online.eu/en/deutschland/muenster/ochtrup-st-lambertus/
In my initial scroll through these registers, I could not find any family members with the last name of Gras/Graas among the entries. I may misread the 1735 marriage record for Maritje Barents. Right now, no luck in finding Herman, Maritje, Everhardus or Jan Graas in the register.
Bummed.
