Hello!
My half-sibling, with whom I don't have any communication whatsoever, made a genealogical tree of our shared ancestors with omission of me as a son of our father. However, I am more dissatisfied with the fact that he, as an offspring, a daughter of my father, listed his half-sister, which is actually from a different father. Do I need to submit any evidence in terms of legal papers and alike that this listing (if it is not a technical error on creator's behalf, than it is libelous) to this site in order to "correct" this listing of a "fake daughter" of my father?
