Locating a divorce record gave me a new spelling for my grandmother's maiden name of Trautvetter. The new (to me) variant is "troutfitter." I performed a google search for the name, finding many references. Most of the sites had to do with fishing and I was initially confused. It took me a few minutes before I realized most of the "troutfitter" references were a play on the words "trout" and "outfitter." Then it made sense, but I also realized that for the majority of the pages I located "troutfitter" was not based upon someone's name. Oh well.
Remember that there is a word outside of genealogy. I will still look for Troutfitter (and Trautfitter) references, but won't assume they all have to do with with the last name.
And my google searches will be constructed to not include webpages that have references to "trout" or "fish."
