If You search with Grunewald a Wendelin can be found:
Grunewald, Wendelin 23 Jun 1891 29 Apr 1891 Kronental 87 Grunewald, Johann Striv ?, Ekaterina Grunewald, Wendelin Schneider, Cecilia
First date is baptism, second is birth date. Keeping the same given names across families was and is very common.
Your query is interesting for me since Grunewald (or Grunenwald etc.) is on my list of ancestors, too. A Franz Herbst (* Feb 1840) was married to Johanna (or Joanni) Grunewald. Two of their daughters play a role to me. Elisabeth born 1873 in Kronental is my greatgrandmother. She first married a ? Kratchmer and as a widow my greatgrandfather. Descendents from both families, Herbst and Kratchmer emigrated to Canada in 1910. No wonder, that Grunewalds did also follow.
