While at www.google.com searching for the Sprowls families, I had a result for a patent that had been filed in 1907 for a wrench by Frederick A. Sprowls. This was the original drawing and patent application. I did some generic searching for other family names, and it turned out to be quite an interesting play time. lol I thought I would share the url, just in case you would like to check out the search engine. Have fun and hope you find someone interesting. www.google.com/patents Ruth Sprowls
