Is there an address for correcting Index errors. By sheer luck, I found my father's family on the 1920 Census Index, because the last name had been mis-spelled. The name in the index was Creig instead of Craig. I happened to find it by sheer luck, looking down during my research for my Mitchell ancestors, and just happening to notice William S, Creig and family directly below the Mitchell(s) I was looking at. The address is correct on Vickers Ave in Lewes, and being 1920, it lists my grandfather, grandmother, and three aunts, Bessie, Ada, and Elizabeth. Is there any way of updating the Index, or is it to be left forever incorrect?
