Help requested to decipher a name

ConderKarenS

I am trying to decipher the name of my 4x great grandmother. She is the wife of Jakob Wyllamowsky (Gregersdorf, Johannisburg, Allenstein, Ostpreussen, Preussen – late 1700s/early 1800s). I have seen her name on several baptismal records and her marriage record. It is usually abbreviated M. M. or Miya Miya. I believe her first name is Maria or Marie, but can’t make out her last name. I think it is something like Meyckria. Can anyone look at these examples and give me any advice on what her surname may be?

Thanks so much.

Thank you.

Maybe it would be a good idea to post this question also in the Polish group as the name may be of Polish origin?
