William Hatfield and Bretha Rice

I would like to find some information on the parents or William Robert HATFIELD who was maried to Bertha Olive RICE. I was told that they were both from South Dakota but have also received that his father may have been from Wisconsin and his mother from New York. I have not received proff of this as of yet so it may not be true. I would also like to find information on the parents of his wife Bertha RICE. I know her fathers names was Charles RICE but have no further information.
