I have been researching Daniel Bruner (My great grandfather) who owned and operated woolen mills in Westmoreland, Clarion and Mercer Counties in approximately 1860 until his death in 1892. He was born in Philadelphia. I have been reading everything I can find on the history of Mercer County. Also looking for information of the Rowland families of that area. I just finished reading the historical information on your site. Very interesting. I enjoyed it very much.
