I've recently received an Ohio death certificate and obit for an ancestor and both these documents list her mothers maiden name as YOP.
Can anyone tell me about this name, if its unusual or in what areas of Germany it may be concentrated?
The mother, Magdalina YOP Butzer Green (AKA: GRUN) was born in Germany c. 1813 and died in Youngstown, Ohio in 1896. She and family emigrated in 1854 under the name GRUN which was changed eventually to Green.
I checked dastelefonbuch.de and there was only one hit for YOP and that was in Eppertshausen, a municipality in southern Hesse in the district Darmstadt-Dieburg (per Wikipedia). Could YOP be a misspelling of YOPP or JOPP?

Thanks for any suggestions.
