Judy, just out of curiosity, went back to look at the 1930 Census page for Frederick in Miami and I'm no expert on handwriting either, but I think that William is HORE. I blew the image up to 75 and 100%.
I can why your expert thinks the H is a W because alot of the H's have a "swoop" a the top of the H but I looked down the page to Homer H. Garrett and the H's are exactly the same - rather plain. IMO.......... just in case it ends up being a meaningful detail later on.
Also, this didn't come up the first time I searched and I doubt if related but just in case.......
