Looking for information regarding this couple. Mary Susan Windle Butler/Beardsley was the dau. of Adam and Hannah Nelson Windle. She resided in Springfield, Hampshire Co., WV. I know of three marriages the last being to a William Orian ANDERSON born about 1856 in Huntington, IN. At the time of this marriage he had been living in St. Joseph, MO.
William Orian Anderson had been married previously as there is an item in a local Hampshire Co.newspaper that mentions his visiting there with his son.
I suspect the marriage was short lived due either by death or divorce. The 1920 census lists Mary Susan, but not as Mary Susan Anderson.
If this looks like your ANDERSON family, I would be pleased to hear from you. I also have an ANDERSON connection in that Mary Susan Windle Butler/Bearsley/Anderson's grandmother was a Hannah ANDERSON from Winchester, Frederick Co., VA who wed a John Richard NELSON about 1832.
