Hi Janet, All though he is probably not related to you , you may find the history of Louden Nelson quite interesting. There is a site for the Louden Nelson Community Center which was established in his honor. It is in Santa Cruz California. I have spent many, many hours there, involved in various activities.
Louden Nelson was an African American slave who bought his own freedom and saved enough to buy property in Santa Cruz which he deeded to the City when he died.
