I am trying to find my great grandmother Mary McDermott parents. She arrived in Sully Co., SD abt 1895 and married John Thomas Galligar. There is a marriage record in Hughes Co., Court house record BK A #197 showing a Mary Whitaker whom married a John Thomas Galigar. Could someone go look at this and verify that he married a Mary Whitaker and not Mary McDermott? Could she have been married before? Would it list who her parents were?
