Actually, we do know the exact spelling of Bickers back to Robert Bickers of Virginia, 1709-1808. Many documents, including his will give it as Bickers. He was my 5th GGrandfather. On another note, my 3rd GGrandmother, Nancy [Todd] Bickers, was one given in the census as Nancy Bakers. You just have to watch not only spelling, but how it sounds. I'd check with the local county archives/library to investigate further to see if your Victor & the 1880 Victor is an absolute provable match. Good luck & hunting!
