I have a book "My Mather Tree",researched by Eunice Leola Mather and Zimmerman Beightol. My mother-in-law was a Mather before marriage. There are several William Mathers listed in it.William born 2/12/1854, died 6/18/30. Married to Julia Evaline Sutton. they were from Nebraska.than it skips to a Willet born in 1884, no other info on him. but there is a 30 year gap in the history.maybe your info fits this gap. if interested contact me and I will ask my motherinlaw for contacts for you. This book was published for her family, don't know if you can buy it any where or not but it has people listedfrom 1766 through 1985.
