There is a book "Cemeteries of Wilson County, Texas" by Irma M. Meyr, listing over 130 cemeteries and burial plots in Wilson County. I have a copy. I don't know if any are still avaiable or not. The book cost $25.00 when I got mine. The Wilson County News did sell them I think. They have a website, try the GOOGLE search engine. I can do a lookup for you if you give me as much info as you can on names, dates or areas of the county where they lived, if you know them.
There is no list of Wilson Co. cemeteries posted. I could copy the index pages and mail them to you if you would like.
Let me know.
