When doing a search I turned a name, with an expected father's "Butler" surname, but with a mother's name of ''Olm F. Knm". Does this mean something?
@michael fichtner It's probably a reasonable assumption that an indexer was not able to make out the surname of the mother properly and made a guess as to what it was. The source film for this record is not available to view online at home. But, you can view it at a family history center and see for yourself what was written on the certificate. Some centers are beginning to re-open. Many of them are open by appointment. Here is how to find what you'd need at the center in order to find the certificate. From the record details page:
If you need to find a family history center near you, click the question mark icon in the top-right of any FamilySearch page. Then click Contact Us. You can let the system access your location, in which case it will find the family history center for you. Or you can enter your location in the "Find a Family History Center and FamilySearch Affiliate Libraries" search box. Entering a city and state works well. On the map that comes up, the bluish icons with a tree are family history centers. Orange icons with a book are affiliate libraries. The specific film you'd need is not available at affiliate libraries, so go with the bluish icons. Click an icon and you'll get the address, hours, and contact info. Probably wise to call before you visit, given current COVID circumstances.
As the marriage source gives Sophia's father's name as John Miller, I would try the census records for 1900 & 1910 for clues. I had a quick look myself and could only find a Sophia Miller (with father John) at https://www.familysearch.org/ark:/61903/1:1:MSJ6-JY6?treeref=G9QG-GSZ.
After marrying Fred, the couple appear to have lived in Nassau, New York, so perhaps there is a link here, in spite of the marriage itself taking place in New York City.
Update - After writing the above, I did a search on "Sophie" (rather than "Sophia", but still with father "John") and got census results as found here: https://www.familysearch.org/search/record/results?treeref=G9QG-GSZ&q.givenName=Sophie&q.givenName.exact=on&q.surname=Miller&q.birthLikePlace=United%20States&q.birthLikePlace.exact=on&q.birthLikeDate.from=1894&q.birthLikeDate.to=1898&q.residencePlace=new%20york&q.residencePlace.exact=on&q.residenceDate.from=1900&q.residenceDate.to=1910&q.fatherGivenName=john*&q.fatherGivenName.exact=on&count=20&offset=0&m.defaultFacets=on&m.queryRequireDefault=on&m.facetNestCollectionInCategory=on
