Charlotte Bitler and Mary Ann Yetter were cousins. Charlotte was the daughter of Samuel Bitler b. November 16, 1788 in Berks Co., PA d. August 14, 1872 and Catherine. I do not have any information about Catherine but she is mentioned in the will of Samuel Bitler. Charlotte is also named in that will as deceased. She died October 23,1865 in Kirksville, Adair Co., MO. The will refers to her heirs.
Samuel Bitler's will corrects a lot of previous errors in Bitler genealogy.
