Mary Ann (Haines) Strout

I am looking for the parents of May Ann Haines. She was the wife of James Cyrus Strout. I have that she was born in Brownfield, Maine on 22 Mar 1833. I have no proof of this. Also she died in Raymond, Maine on 20 Jan 1875. I did find a picture of her stone on Findagrave.com

Any help is appreciated, Thanks, Scott
