This is a big help. I was able to find the record you provided on Ancestry. It's not "my" Gossett, but you've given me a new place to look for information.
Just as an FYI, the William T. Gossett I'm looking for was married to Parmelia Frances Tarter. They lived in Bennington, Bryan County, Oklahoma. He was working for the post office in 1918 and by the 1920 census, he wasn't working and died about a month later at age 36. His 2 brothers also died young. His son, and my grandfather, died at age 54. It has me curious.
I hope you have a wonderful day.
