I have been researching the Knowles family as part of my research into the Lee family in Yonkers. Anna Edna Cody born in CT in 1891 married William Anthony Knowles on 21 May 1911 in Yonkers. They had one daughter Martha Marie born in 1912. William and Anna separated ( divorce) and she Edward Howell Stickney ( 1885-1973) married sometime around 1925. Martha went to live with her mother and stepfather in the Bronx. Martha later married Ferrall Hetherington in 1942. They also divorced. I do not know if they had children.
