Thank you Herbert. I had found this yesterday.
She first married Christopher Lavinway, having a son, John Lavinway. She then married William Hazely. The Census records show John Lavinway as John Hazely. After John moved out and married, he took his birth name. I only figured this out after finding him as on 1900 census listed as head of house, Saray Hazely, his mother, William Hazely, his STEP-father!
