The Eisenzimmers/Eisenzimers of Louisville, Ohio

I am researching the Eisenzimmers of Louiseville, Stark County Ohio, originating in Alsace-Lorraine and possibly before that Germany. Some members of this family spelled their name "Eisenzimer".
I am also researching the Wertz family of Paris, Ohio, Stark County.I have gained a great deal of information from the Wertz family website, but would like more on this specific family.
In addition, I am researching the Beovic/Beovich family of Pensacola, FL, originating in Croatia which at that time was either Yugoslavia or Austria.
I would also like information on the William V. McNeir family of Pensacola, FL, and Baltimore, Maryland.
