Nothing specifically Halloween oriented, but almost everyone can come up with something either from local lore or personal happenings that fit into the scary mold!
My great (#?) grandmother escaped from the Trail of Tears and was married at a very young age to a man who basically hid the fact of her Cherokee heritage--which really wasn't that unusual considering the attitudes of the times. Much later in life she wrote a letter detailing what happened, so we have that, but it is considered only anecdotal proof--nobody in the family was 'allowed' to sign up when the Dawes' Rolls were established--not by the government authorities but by other family members, who were afraid of the reason for the sign-up.
