The image above is part of an affidavit made by Focke J. Goldenstein in his homestead application for property located in Dawson County, Nebraska. Not all applications contain such statements, but there were irregularities in the transcribed names for Goldenstein in several of the documents and this affidavit was made in response to those inconsistent spellings. It is not often that affidavits clearly spell out exactly the name that our ancestor preferred. I'll have to go back and see exactly what is on his tombstone.
Of course, when transcribing documents the spelling on the document is used. One does not "correct" records when transcribing them. Notations or comments can discuss any irregularities on the document in regards to names.
I once had a genealogist tell me I was spelling "Focke" wrong and that I should use "Fokke" instead. Based upon this record, I'm using Focke.
