Hi, The town of Ault (Weld County) was named for a grain mill owner named Alexander Ault.I have forgotten his exact relationship to the Ault families of Jefferson County but I think he was a first or second cousin to Andrew J Ault (b. 1830) and Francis M Ault (b. 1842).(They were two of the sons of Leonard Ault of Coshocton, Ohio; both later lived in Wisconsin and in other places in the midwest before coming to Colorado.)I don't recall that there were many Aults buried in the Ault Cemetery in Weld County, but there are a lot of Aults (living and dead) in various parts of Weld County.http://www.findagrave.comhttp://www.findagrave.comis a useful resource.There is also a Colorado GenForum grave registry website, I think.
