I recently came across an Ancestry tree, from a lady in America with my grandfather in and a word document I had written about him attached to his name, when I looked they have his sister in the tree three times, her name was Harriet Agnes, but they have her as, Harriet, Agnes, and Harriet Agnes plus a brother under two names! Also they have my great grandfather married to the wrong woman, with a correct photograph of my great grand parents headstone, which clearly shows her maiden before marriage, not the one in her tree! All part of the thousands of names she has in her tree.
