What is the relationship between ISAAC SHEPHERD (43), wife, REBECCA (29) & ROBERT COOPER (40)& ANNIE COOPER (35) all listed in the 1880 census for Polk Co., Fl. Isaac is head of Household. 1. Robert brother to Rebecca? 2. Annie sister to Isaac? 3. Robert & Annie renters from Isaac? ALSO...... I have MINNIE COOPER (my grand-ma)listed at age (3) in the 1880 census for Starke, Bradford Co., Fl. with MARY COOPER listed as Head of Household, with 5 children. NOW..... MINNIE's Death Certificate has ROBERT COOPER listed as Father.Are these two Roberts the same and if so what is the maiden name for Minnie's Mother?
