After looking at the 1910 Henderson Co. NC Census, I'd say that William Taylor died 1916-1919 in either McDowell or Henderson Co.
The Searcy Family Tree (Ancestry) says that he died 17 Jan 1918, Hoopers Creek, Henderson, NC and was buried in Skyland, Buncome Co. NC but no sources were provided.
I'd contact the Henderson County Genealogical & Historical Society, www.hcghs.com/index_files/Page460.htm
and ask if they have a local death index, indexed newspaper death notices or obits.
There is also a Zachariah Taylor 'Zach' Searcy b. 21 May 1873, Rutherford Co. NC who died 1947 in Rutherford Co. NC. People seem to confuse these two different men. Successful Searching!
