Curious abt Robert GREENOUGH, b. abt 1817 in Maine, and his wife or sister, Jane, b. abt 1807 in Ireland. By 1857 they were in Minnesota Territory with a 4-yr-old girl named Julia CASSELLE, b. abt 1853 in NY. Julia's mother was Eliza CASSELLE (CASTLE), father unknown. By 1870 Julia (aka Mary Julia)had changed her surname to GREENOUGH and m. Wm H. EVERETT. Anyone familiar with this family?
