Annie Amelia Abbott born 1860 in Lincolnshire UK could be the person you want. Three of her brothers, Thomas, Edward and Robert emigrated to Iowa earlier. If it is the same person it could be her second marriage. The first being to William Rhodes in 1856. She had a child William Cecil Rhodes in 1894 at Well, Lincolnshire. Parents were Thomas Abbott born 1821 in Belchford Lincolnshire married to Anne (nee Clement). If this is the right person I have the Abbott tree back to 1605.
