Heimberger of PA, WV, Germany

My grandmother was Bertha Minnie Heimberger (Manners), born in Bentwood WV 28 Aug 1893.She lived most of her life in Indiana County, Pennsylvania.

Her parents were Wilhelm Heimberger (b. 17 May 1859 in Baden, Heidelberg Germany; d. 24 Dec 1935 in Bell Township, Westmoreland County, PA) and Anna M. M. Gerke (Heimberger)

Wilhelm's parents were Phillip Heimberger and Theresa Huffman, who I *assume* never left Germany.

I'd like to correspond with anyone working on this line of Heimbergers.
